Abstract:
Single box sections and T-joints (two box sections joined together at right angles) are commonly used to represent automotive components, such as pillars and sills, in laboratory testing. In the work presented herein, the torsional properties of T-joints were determined both experimentally and numerically. A factorial-design test programme comparing adhesive-bonded and spot-welded T-joints was carried out. Numerical models, generated using a general-purpose finite element program and validated against the test results, were used to investigate further the behaviour of the connection between the two box sections in a T-joint. The joining technique and the joint eccentricity at the connection (the distance of the join from the vertical box section) were found to influence the torsional properties of T-joints. Finally, an automotive T-component was analysed to examine the applicability of the T-joint results to more complex components.

Abstract: The weld joints are used in various types of mechanical and civil engineering structures to strengthen the joints. The strength of T shaped weld joint significantly depends upon the design parameters of weld joint. The current research is intended to investigate the T shaped weld joint using techniques of Finite Element Analysis (FEA). The FEA analysis is conducted on T shaped weld joint using ANSYS simulation package. The optimization studies are conducted on T shaped weld joint to determine the effect weld joint parameters on induced deformation. From the optimization studies, the dimensions corresponding to weld height is determined for maximum and minimum deformation of T shaped weld joint.

Abstract:
For typical tubular T-joint, the common failure generally occurs near the weld toe on the chord surface due to the fact that the stiffness of the chord in radial direction is much smaller than that of the brace in axial direction. In this paper, the static strength of tubular T-joints is improved by filling concrete into the chord. The finite element method is used to investigate the improving effeciency of the static strength for tubular T-joints with filling concrete in the chord under axial compression and tension. Firstly, 6 T-joint models were analyzed to prove that filling concrete in the chord is effective to increase the static strength and the stiffness of T-joints with hollow section. Afterwards, based on the analyzing mechanism for CFCT T-joint under axial compression and tension, the different performances under axial compression and tension between circle hollow tubular T-joint and CFCT T-joint were clarified, and the different failure modes for tubular T-joints with hollow section and CFCT T-joints were compared and analyzed.

Abstract:
This paper investigates the behaviour of square hollow section (SHS) T-joints under static axial tension for the determination of stress concentration factors (SCFs) at the hot spot locations. Five empty and corresponding concrete-filled SHS-SHS T-joint connections were tested experimentally and numerically. The experimental investigation was carried out by attaching strain gauges onto the SHS-SHS T-joint specimens. The numerical study was then conducted by developing three-dimensional finite element (FE) T-joint models using ABAQUS finite element analysis software for capturing the distribution of the SCFs at the hot spot locations. The results showed that there is a good agreement between the experimental and numerical SCFs. A series of formulae for the prediction of SCF in concrete-filled SHS T-joints under tension were proposed, and good agreement was achieved between the maximum SCFs in SHS T-joints calculated from FE T-joint models and those from the predicted formulae.

Abstract:
T-joints are often used in large-scale welded constructions. The use of a laser beam for welding allows to create joints using various techniques. Used welding method affects the shape and size of heat affected zone, deformation of welded elements and consequently the quality of the joint. This work concerns the numerical modeling of the size of heat affected zone and welding deformations in T-joint obtained with two different welding techniques: single-side fillet T-joint and butt welded T-joint, called I-core welded joint. Numerical simulations are carried out in the commercial Abaqus FEA software, supplemented by an additional numerical subroutines which enabled the analysis of thermomechanical phenomena occurring in welding process. Mathematical model of a moveable welding source and the description of heat source positioning relative to the edges of the connected elements are described in numerical subroutines. The material parameters of austenitic steel are taken into account. The size of deformations of welded joints are determined as well as the influence of two different joininig techniques of T-joint on the amount of generated welding deformations are analyzed and compared.

Abstract:
This paper deals with the analysis of sandwich T-joints in terms of buckling loads, which are used in marine applications. Buckling loads have been investigated experimentally and numerically. Loading is applied as uniform axial compression. The GRP/PVC sandwich composite T- joints have been manufactured in six different geometries. Numerical and experimental results both show that the geometry of the T-joint area affects the buckling loads. It has been observed that failure mode is the same in all of the joint types, which is core shear. Stress distributions in T-joints have also been investigated under buckling loads and also for a constant compression load. It is seen that T-joint geometry has an effect on stress distributions obtained under buckling loads.

Abstract:
Currently, self-piercing riveting (SPR) is a major technology used by manufacturers to join aluminium body structures to reduce vehicle weight. Normally, for SPR of one specific stack more than one die, rivet, and velocity combination can be applied. Which parameter combination is chosen is depending on the surrounding joints. In order to increase productivity and reduce the number of robots used, it is preferred to use the same rivet/die combination for as many joints as possible. This means for the same stack, different die may be used. To see the influence of die profiles on joint quality, a DF die, which would generate severe cracks and a DC die, which would generate no cracks or only small cracks, were used to join two stacks with a high strength aluminium alloy, AA6008T61, as the bottom layer. The joint quality was analyzed, and the static and fatigue strengths of these stacks were studied. Results showed that cracks on joint buttons might reduce static and fatigue lap shear strength but had no obvious influence on static and fatigue T peel strength for the joints studied.

Abstract:
This study aimed to obtain a better method for establishing a finite element model of mortise-and-tenon (M-T) joints. Three types of M-T joint finite element models, which included a whole rigid model, a tie rigid model, and a semi-rigid model, were established and compared with experimental results by predicting the bending moment capacity (BMC) of M-T joints based on the finite element method (FEM). The results showed that the semi-rigid model performed much better than the tie rigid model, followed by the whole rigid model. For the semi-rigid model, the ratios of FEM ranged from 0.85 to 1.09. For the whole rigid model and tie rigid model, the BMC of the M-T joint was overestimated. In addition, the results showed that tenon size remarkably affected the BMC and stiffness of the M-T joint, and tenon width had a greater effect on the BMC of the M-T joint than the tenon length.

Abstract:
This Master Thesis was performed in terms of robotic three dimensional friction stir welding with T-butt joint. Friction stir welding (FSW) is a solid state welding method that achieves the weld temperature by friction of a rotating non-consumable tool with the workpiece. Science and technology fast developing requires for higher seam quality and more complex welding joint geometry like 3D welds. In order to acquire high productivity, capacity and flexibility with acceptable cost, robotic FSW solution have been proposed. Instead of the standard FSW machine, using a robot to perform complicated welds such as, three-dimensional. In this report, a solution for weld a 3D T-butt joint, which located in an aluminium cylinder with 1.5 mm thickness using a robot, was developed. Moreover, two new paths were investigated in order to avoid the use of two welds to perform this type of joint. The paths were tested on 2D and on 3D (with a 5050 curvature radius) geometries. Both paths had good results. What is more, the parameter developing methods of FSW process, which is composed of necessary parameter setting, positional compensation was introduced. Specially,the study demonstrates how complicate geometry can be welded using a robot. Also,it shows that TWT temperature control is able to acquire high quality 3D welds. In addition, an analysis of the 2D welding and 3D welding was performed, which exposed that, keeping exactly the same welding conditions, higher lateral forces on the tool were found during 3D welding. Basis on the special case in this paper, when the tool goes like "climbing" the sample, the suffering force of tool decreasing with increasing the height(Z position); nevertheless, when the tool goes like "downhill", the suffering force of tool decreasing with decreasing the height (Z position). What is more, in 2D weld, increasing the downforce (Fz) results increasing the lateral forces which can be Fx and/or Fy. Finally, the future works suggestions were presented in terms of (1) performing the new paths into a real cylinder, (2) performing tensile test on the paths and comparing it with conventional path which weld twice, (3) researching how the downforce (Fz) influence the Fx and Fy during welding of different 3D geometries, (4) how the cooling rate of backing bar influence the seam quality when it is use the same welding parameters and (5) the effect of performing welds in the same welding temperature achieved with different combination of the tool rotational speed and downforce on the material properties

Abstract:
The welding process introduces residual stress originating from the heating, melting and cooling of the material. From the point of view of fatigue and stress corrosion cracking, the weld residual stress perpendicular to the weld axis is of particular interest. When qualifying weld parameters for welds in large cylinders having a ratio of radius to plate thickness larger than say approximately 100; reference to plane plates are often made for the sake of simplicity. However, the weld residual stress perpendicular to the weld axis is severely underestimated in the plane plate compared with the cylindrical structure. This observation is especially pronounced in connection with preheating. The source of the differences is probably due to the radial constraint of the cylinder, compared with that of a plane plate. A plane test specimen will underestimate the weld residual stress perpendicular to the weld axis in a cylinder, even if the radius of the cylinder is very large. However, a test specimen for an 8 m diameter cylinder with a plate thickness of 35 mm needs only to have a segment width of approximately 1.3 m to reflect the stress in the real structure. The weld residual stress perpendicular to the weld axis in the vicinity of the weld toe is governed by the depositing of the weld bead adjacent to the weld toe, neglecting the accumulated strain from the previous deposited weld beads in the multi-pass joint weld. Introducing tensile straining perpendicular to the weld axis during the entire welding procedure reduces the weld-induced residual stress after completed welding. The plastic zone of the weld area will be subjected to compressive strain after completed welding, which in turn will reduce the weld residual stress. This can be achieved by cooling the weld area, which in this case is not recommended since the material is sensitive to hydrogen cracking, or by pre-stretching or modifying the locations for preheating, all aimed to impose a tensile axial straining around the weld area during the entire welding process.

Abstract:

Following a short introduction, the state-of-the-art fatigue life assessment methods based on the nominal stress, the structural hot spot stress and the effective notch stress, as well as the crack propagation analysis are explained and discussed.

Thereafter, the effect of mean stress on crack propagation was investigated by exemplifying crack propagation data from different aluminium alloys. In this context, Walker's equation received wide attention. In addition, a new, simple equation to express the mean stress dependency of crack propagation data has been proposed.

In order to generate crack propagation data for the 6082-T6 aluminium alloy, investigate the behaviour of short cracks and find the mean stress dependency of crack growth in this alloy, crack propagation tests of sub-millimetre cracks subjected to different stress ratios have been carried out. The crack depth was successfully monitored on-line employing a special direct current potential drop technique. The crack propagation data generated verified the long crack propagation data given in Eurocode 9. In addition, useful experience was gained to improve future tests. Some evidence was found of accelerated crack growth near the threshold. Based on the data obtained and literature data a Walker exponent γ= 0.78 has been calculated for the aluminium alloy 6082-T6.

The fatigue life of welded aluminium T-joints has been estimated using the approaches introduced in Chapter 2. The results have been compared with experimental data from T-joints subjected to 4-point bending. In addition, a series of T-joints subjected to transverse bending has been fatigue tested and the results have been compared with predictions using the same fatigue life assessment methods.

The nominal stress gave a conservative prediction in case of the 4-point bending loading. Since no applicable detail category for the transverse bending load case exists, a suitable detail category has been suggested.

The structural hot spot stress approach resulted in conservative predictions (factor 4-10 in life) for both load cases.

The predictions from the effective notch stress approach are in excellent agreement with the experimental results, where the method using a 1 mm weld toe radius gave the best results. It has been shown that the method can be successfully applied to joints with wall thicknesses down to 3 mm.

The fatigue life predicted with the crack propagation approaches is in excellent agreement with the experimental results from the 4-point bending load when the Mk factor was used. Applying the local stress distribution, the predictions are conservative for both load cases.

The slopes of all predicted S-N curves, especially from the stress based methods, are steeper than the experimental curves.

Abstract:
Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. The Virtual Manufacturing Process research group at University of Skövde wishes to increase their knowledge on modeling options of thermomechanical simulations to grant local industries these benefits. A numerical model for the laser welding process was developed in ABAQUS. This was done by examining the macrograph structure of a simple weld and applied to a stainless-steel T-joint welding application. The macrograph data was used to calibrate a mathematical heat source model. User subroutine DFLUX was used to enable movement of the heat source and element activation was used to simulate the fusion of the two parts. A T-joint welding experiment was carried out to measure deflection and the result was compared to numerical simulations. Different combinations of heat source models, coupling type and element activation was compared in relation to predicting the deflection. Computational time and modeling complexity for the techniques was also considered.The results showed that a 3D Gaussian heat source model will imitate the keyhole weld achieved superior to the compared 2D model. The 3D model provides greater flexibility since it enables combinations of any geometrical bodies. It was shown that element activation has a significant contribution on part stiffness and thus resulting distortions. To implement element activation a fully coupled analysis is required. The deflection of the fully coupled 3D simulation with element activation showed a 9% deviance in deflection compared with experiments.

Abstract:
Wind turbines are classic examples of structures where their operating lifetime is controlled by the fatigue properties of the material. This is exacerbated by the 2D nature of the composite materials used in blade construction which are typically fabrics in a variety of formats (e.g. non crimp fabrics, uniweave, woven). The formation of internal detailed shapes within the blade, allowing features such as spars, shear webs and other connections, inevitably requires these 2D material configurations to be formed into 3D shapes. This introduces positions within the structure where load transfer occurs across regions with no fibre reinforcement. These weak areas become natural positions for the initiation of damage that can occur well before fatigue damage would be expected in the basic material subject to simple in-plane loading. The aim of this study is to modify and improve the blade structure in order to extend its working life and minimize geometry related fatigue issues. To achieve this goal T-sections have been manufactured as representative element of the blade's spar. T-sections have been made of carbon or glass fabric infused with epoxy resin using a vacuum-assisted resin-transfer moulding technique. The structure has been modified with different toughening techniques to increase its interlaminar fracture resistance (toughness) and hence delay or stop crack propagation. Methods such as the use of veil layers, tufting and 3D weaving techniques have been employed to improve the interlaminar fracture toughness of the T-joint. The changing parameters in samples are, the addition of the veil layer to the composite structure, veil material, tufting stitches and use of different 3D fibre weaving architectures in the fabrication of the composite T-joint. For T-joint testing, there was no standardised specimen shapes and no standard for specimen dimensions; as well as no test fixture designs or test procedures. Consequently, it was required to design a test rig and develop a test procedure for tensile and fatigue tests of T-joints. An additional investigation was performed to establish test specimen geometry suitable for testing in available Instron machines. Manufactured specimens were quasi-static and fatigue tested. Test results were compared and showed that 3D woven and polyester veil T-joints had the best performance among modified structures. However, it has been found that these structural modifications are performing differently in quasi-static and fatigue loading. The 3D woven four layer to layer inter wave sample that showed the best result in a quasi-static test was not the one with the best fatigue results but it was amongst the ones with the highest performance. SEM and optical microscopy were used to investigate fractured specimens in an attempt to establish the mechanisms involved in the fracture process of the T-joint. Finally, based on test and investigations results it has been concluded that the 3D weaving was the most effective modification to improve the static and fatigue properties of the T-joint. The T-joint modified with polyester veil showed the second best performance in both static and fatigue tests but the addition of the polyamide caused had negative effects on these properties.

Abstract:
Dans ce memoire, il s'agit de la modelisation du soudage d'un joint en T par la methode des elements finis. Le but du modele est de prevoir les deformations et les contraintes residuelles associees au soudage des plaques. Le modele peut s'adapter pour ameliorer le procede du soudage en variant les parametres en jeu tels que la geometric du chanfrein, I'intensite du courant, le depot simultane des deux cordons, la vitesse de la torche, etc. L'experimentation est faite sur deux plaques de 3/8 pouce d'epaisseur (9.5 mm) et de 10 pouces de longueur (254 mm). La largeur de la premiere plaque est de 10 pouces (254 mm) et celle de la deuxieme est de 6 pouces (152.4 mm), celle-ci est soudee perpendiculairement au centre de la premiere. La deuxieme plaque est faite avec un chanfrein de preparation de 'A pouce (6.35 mm) de hauteur et faisant un angle de 30 degres de chaque cote. Pour avoir les parametres de soudage les plus precis possibles, le robot SCOMPI^ est utilise pour la realisation des essais. Les parametres du soudage sont de 26,9 Volts, 220 Amperes et une vitesse d'avancement de 5 mm/seconde. L'efficacite du procede est estimee a 77 %. La simulation sert a predire numeriquement les temperatures, contraintes et deformations lors du soudage. La demarche de la modelisation est divisee en deux parties : la simulation thermique et la simulation structural. La methode « birth and death » est utilisee pour la simulation du depot du metal d'apport, et le modele du double ellipsoide propose par Goldak, Chakravati et Bibby est utilise pour I'apport de la chaleur. Durant la simulation du depot du metal d'apport, une relation entre I'incrementation du temps et la taille des elements est faite. L'analyse transitoire est faite en fonction de la position de la torche plutot qu'en fonction du temps. Les resultats thermiques de la simulation se comparent bicn a ceux de I'experimentation. Une difference maximale de 1,5 % a ete observee avec des temperatures comparables. Ces temperatures sont obtenues de thermocouples colles sur la plaque horizontale (THi). Les proprietes non lineaires du materiau en fonclion de la temperature sont utilisees. Aussi, il y a une presentation d'une nouvelle fa^on pour le calcul du coefficient combine (radiation-convection) de perte de chaleur en fonction de la temperature. Les ecarts structuraux varient de 6.6 % pour la contrainte principale et jusqu'a 32.9 % pour le deplacement du cote de la deuxieme passe. L'ccart sur les deplacements est surtout lie a 1'incertitude de la rigidite du gabarit. Le modele numerique reflete bien la realite. La facilite de varier ces parametres geometriques. thermiques et structuraux le rend flexible pour simuler plusieurs soudages de joints similaires. Une amelioration du controle des conditions frontieres et d'autres de modeles de source de chaleur sera utile pour des travaux futurs.

Abstract:
Adhesively co-bonded and co-cured structural joints are attractive for aircraft applications due to the potential reduction in weight and part count as compared to traditional mechanical joints. In this research, a damage tolerant structure using co-bonded hybrid T-joints was designed and manufactured for structural application on a remotely piloted aircraft. The T-joint structure was constructed from GLAss fiber REinforced aluminum laminates (GLARE) 4-2/1 skin, carbon fiber composite web, and three-dimensional woven glass fiber fabric Pi-preform in a co-bonded/co-cured process. The goal of this research is to demonstrate the damage tolerance, structural capability, and ancillary benefits of the co-bonded T-joint. In order to evaluate the structural design and investigate the strength of manufactured T-joint, experiments such as pull-out tests were performed. Additionally, the T-joint was manufactured and tested with defects inserted intentionally within the co-bonded interface between the GLARE and Pi-preform at two locations: a) underneath the vertical woven carbon composite web, and b) along the edge of the glass fiber Pi-preform and the GLARE flange. Pull-out tests showed the effect of intentionally inserted defects on the strength of the co-bonded T-joint structure. The benefit of co-bonded joints featuring damage tolerant skins and high strength composite webs has been demonstrated.

Abstract:
The cost of damage to the non-structural systems in critical facilities like nuclear power plants and hospitals can exceed 80% of the total cost of damage during an earthquake. Studies assessing damage from the 1974 San Fernando and 1994 Northridge earthquakes reported a widespread failure of non-structural components like sprinkler piping systems (Ayer and Phillips, 1998). The failure of piping systems led to leakage of water and subsequent shut-down of hospitals immediately after the event. Consequently, probabilistic seismic fragility studies for these types of structural configurations have become necessary to mitigate the risk and to achieve reliable designs. This paper proposes a methodology to evaluate seismic fragility of threaded T-joint connections found in typical hospital floor piping systems. Numerous experiments on threaded T-joints of various sizes subjected to monotonic and cyclic loading conducted at University of Buffalo indicate that the “First Leak” damage state is observed predominantly due to excessive flexural deformations at the T-joint section. The results of the monotonic and cyclic loading tests help us evaluate the following characteristics for a given pipe size and material: (i) Maximum allowable value of rotational deformation at the T-joint section to prevent “First Leak” damage state; (ii) The force-displacement and moment-rotation relationships at the T-joint section. A non-linear finite element model for the T-joint system is formulated and validated with the experimental results. It is shown that the T-joint section can be satisfactorily modeled using non-linear rotational springs. The system-level fragility of the complete piping system corresponding to the “First Leak” damage state is determined from multiple time-history analyses using a Monte-Carlo simulation accounting for uncertainties in demand.

Abstract:
Recently, the emerging research between human and robotic device has been adapted to many applications. Collaborative Robot or Cobot is one of promising candidates because it is inherently passive and intrinsically safe. Cobot’s joints are coupled together by CVTs (continuous variable transmissions). The cobot’s endpoint direction can be controlled by adjusting transmission ratios of these CVTs. Former cobots developed in recent years have constant joint-to-joint distances. Some will be reviewed. In this paper, we propose a novel transformable cobot called T-Cobot which has ability to expand the joint distances. We describe the design and construction of the T-Cobot Prototype. In addition, the kinematics of the T Cobot is proposed.

Abstract:
The T-joint is a common joint type frequently used in transport industries because of the importance of increasing the inertia and strength of thin skins and shells without significant weight increase. This shape can be obtained by different processes as extruding, riveting, welding or others. However, the low weldability of some aluminum alloys, when using traditional welding processes, is an obstacle to the possible full benefit of such reinforced structures. The friction stir welding (FSW) process is suitable to join most aluminum alloys and should be considered as a feasible alternative to the other processes used to produce this type of geometry. This paper reports the results obtained concerning FSW T-joints with a new configuration. These joints simulate a typical reinforcement composed by two materials in order to optimize the damage tolerance. The skin is made of a 6xxx series alloy, and the reinforcement is made of a 7xxx series alloy. Mechanical properties were obtained and micro-structural analyses of the weld zone were performed, and the results were compared with those obtained in base materials and butt joints.

Abstract:
This paper presents an experimental investigation into the effects of the application of carbon nanotube (CNT) based nanopolymer, and thin film buckypaper, to the interface of stiffened carbon fiber reinforced polymer (CFRP) composite joints. Bonded CFRP composite T-joints, were manufactured with dispersed CNT epoxy nanopolymer mixture, and buckypaper films, applied at the joint interface, and tested under pull-off loading. The presence of the nanomaterial at the interface causes a localized out-of-plane reinforcement, which resists pull-off loads, leading to superior performance compared to composite bonded joints without nano-reinforcements, however, the introduction of substantial voids, in the case of the buckypaper samples, lead to faster structural failure. Digital image correlation (DIC) was used to map the strain contours of the T-joint specimen during testing, which revealed damage initiation and hot-spot zones. Fluorescent optical microscopy of the joint sections was also performed to investigate these hot-spot zones and damage initiation areas, at the mesoscale, to study the possible causal mechanisms of the failure process in the tested composite bonded joints.

Full text
Abstract:
Residual stress (RS) pattern of thick T-joint welds, which directly affects fatigue life, varies considerably depending on the thickness and number of passes. Nowadays, most approaches to predict fatigue life do not consider RS real value due to the difficulty of estimating them, hence, they tend to be conservatives. However, recent works have demonstrated that considering RS the conservative error in life prediction can be reduced down to around 15%. In the present work, the fatigue performance of multipass T-joints of S275JR plates for a thickness range from 20 to 60mm is evaluated considering RS. It is observed that maximum RS value for thick plates decreases progressively (down to 66% of yield stress). Consequently, fatigue performance of different thickness T-joint samples subjected to the same stress load cycles varies considerably in the HCF regime.

Full text
Abstract:
A mixed cohesive damage model was introduced in this paper to study the delamination of composite T-joint components under pulling load. Prediction together with part of test results was presented in this paper. Modelling prediction had a good agreement with experimental work. This study indicated that the mixed damage scale plays an important role in the progressive damage analysis of T-joint components. The mixed damage scale properly reflected the effects of interaction between different damage modes in simulating damage propagation of an object with strong coupled effects. This coupled damage effect was considered from the material softening stage to final crack. Thus a proper damage accumulation was accounted since materials begin damage. An example given in this paper shown the delamination in the deltoid region of T-joint was simulated very well. Finally, a concept of novel materials was proposed for the deltoid region of T-joint in this paper. Initial investigation by simulating delamination presented that the damage resilience of composite T-joint with novel composite materials in deltoid region significantly improved its damage resilience.
