Ultrastructural changes in lung parenchymal elastic fibers were studied morphometrically 1, 4, and 12 wk after a single 12-unit dose of pancreatic elastase and in a saline-instilled control group. The mean linear intercept of the parenchymal air spaces was increased in the 1-, 4-, and 12-wk post-elastase instillation groups compared with age-matched controls. The volume of alveolar connective tissue fibers predominantly composed of elastin (elastic fibers) was decreased by 35% 1 wk after the instillation of elastase but returned to control levels by 4 wk. Although the total volume of elastic fibers was normal 12 wk after instillation of elastase, the volume of elastic fibers in alveolar entrance rings remained significantly reduced. In serial sections of elastic fibers, numerous gaps or separations in the normally continuous band of elastic fibers that encircle each alveolus were identified 1 wk after elastase instillation. There were 169 +/- 8 (SE), 62 +/- 32, and 12 +/- 6 gaps per millimeter of alveolar entrance ring circumference at 1, 4, and 12 wk, respectively, in the elastase-treated groups. The number of gaps at 12 wk was equivalent to two gaps or discontinuities in the elastic fibers of every alveolar entrance ring. No gaps or separations in elastic fibers were detected at 1, 4, or 12 wk in the control groups. These defects occur in concordance with the progression of air space enlargement and presumably contribute to the progression of air space enlargement that occurs after the elastin content of the tissue has returned to normal.

The elastic-plastic solution for an infinitely long cylindrical shell with an axisymmetric ring load is presented. Except for the material nonlinearity, the standard assumptions of small deflection shell theory were made. Because the principal directions are known for the axisymmetric problem, the Tresca yield condition wasused. This made it possible to obtain closed-form expressions for the elastic-plastic, moment-curvature relations, greatly simplfying the computational task. The actual stress distribution through the thickness was used, making these relations exact. Yielding was contained near the load. Thus, for the analysis the cylinder was divided along its axis into elastic-plastic and purely elastic regions. Solutions were obtained for each region which were then matched at their intersection to give the complete solution. All results are given in dimensionless form so that they may be applied to any shell.

The three dimensional Monte Carlo radiation transport model McArtim is extended to account for the simulation of the propagation of polarized radiation and the inelastic rotational Raman scattering which is the cause of the so called Ring effect. From the achieved and now sufficient precision of the calculated Ring effect new opportunities in optical absorption spectroscopy arise. In the calculation the method of importance sampling (IS) is applied. Thereby one obtains from an ensemble of Monte Carlo photon trajectories an intensity accounting for the elastic aerosol particle-, Cabannes- and the inelastic rotational Raman scattering (RRS) and simultaneously an intensity, for which Rayleigh scattering is treated as an elastic scattering process. By combining both intensities one obtains the so called filling-in (FI, which quantifies the filling-in of Fraunhofer lines) as a measure for the strength of the Ring effect with the same relative precision as the intensities. The validation of the polarized radiometric quantities and the Ring effect is made by comparison with partially published results of other radiation transport models. Furthermore the concept of discretisation of the optical domain into grid cells is extended by making grid cells arbitrarily joining into so called clusters, i.e. grid cell aggregates. Therewith the program is able to calculate derivatives of radiometrically or spectroscopically accessible quantities, namely the intensities at certain locations in the atmospheric radiation field and the light path integrals of trace gas concentrations associated thereto, i.e. the product of the DOAS (differential optical absorption spectroscopy) method, with respect to optical properties of aerosols and gases in connected spatial regions. The first and second order derivatives are validated through so called self-consistency tests. These derivatives allow the inversion of three dimensional tracegas and aerosol concentration profiles and pave the way down to 3D optical scattered light tomography. If such tomographic inversion scheme is based solely on spectral intensitites the available second order derivatives allows the consideration of the curvature in the cost function and therefore allows implementation of efficient optimisation algorithms. The influence of the instrument function on the spectra is analysed in order to mathematically assess the potential of DOAS to a sufficient degree. It turns out that the detailed knowledge of the instrument function is required for an advanced spectral analysis. Concludingly the mathematical separability of narrow band signatures of absorption and the Ring effect from the relatively broad band influence of the elastic scattering processes on the spectra is demonstrated which corresponds exactly to the DOAS principle. In that procedure the differential signal is obtained by approximately 4 orders of magnitude faster then by the separate modelling with and without narrow band structures. Thereby the fusion of the separated steps DOAS spectral analysis and subsequent radiation transport modeling becomes computationally feasible.

Des études récentes ont montré qu’une mesure électrique permettait de caractériser les interfaces multi-contacts. Ces recherches initiées dans les milieux granulaires sont transposées dans un cadre technologique dédié au monitoring et au diagnostic des défauts dans les roulements. Cette méthode innovante exploite la richesse et la sensibilité d’une mesure électrique localisée et corrélée à l’état de chargement d’un roulement. Pour démontrer le potentiel de cette méthode, des mesures électriques expérimentales sont effectuées sur un banc de roulements et l’analyse des signaux révèle des similitudes avec les traditionnelles méthodes de surveillance. D’un point de vue numérique, le roulement est modélisé avec la méthode des éléments discrets (MED), d’ordinaire dédiée à l’étude des milieux granulaires, à partir de laquelle le comportement mécanique du roulement en dynamique est reproduit. Une formulation électromécanique est ensuite introduite pour en déduire une grandeur électrique numérique d’un roulement en fonctionnement, à comparer avec l'expérimentation. Des signatures électriques typiques en réponse à des sollicitations complexes (défauts, jeux, balourds, etc) sont étudiées et l’étude du comportement mécanique des bagues ouvre des perspectives intéressantes pour comprendre et modéliser leur endommagement. Alors que de nombreuses études ont été menées sur le suivi vibratoire des roulements, le recours à une méthode électrique localisée, sans capteur, est inexploité et prometteur
Recent studies have shown that an electric measurement made it possible to characterize the multi-contacts interfaces. The research initiated in granular media are transposed in a technological environment dedicated to monitoring and diagnosis of defects in bearings. This innovative method exploits the richness and sensitivity of a localized electrical measurement and correlated to the bearing load status. To demonstrate the potential of this method, experimentals electrical measurements are performed on a bench and signal analysis reveals similarities with traditional monitoring methods. From a numerical point of view, the bearing is modeled with the discrete element method (DEM), usually dedicated to the study of granular media, from which the mechanical behavior of the bearing dynamic is well reproduced. Electromechanical formulation is then introduced to derive a numerical electrical quantity of a bearing in operation, compared with the experiment. Typical electrical signatures in response to complex stresses (defects, clearance, imbalance, etc.) are studied. Studies of the mechanical behavior of rings opens interesting perspectives to understand and model their damage. While many studies have been conducted on the vibration monitoring of bearings, the use of a localized electrical method without sensor is still untapped and has promising results

One of the many challenges in the behaviour of structures is to understand if the presence of residual stress plays an important role in contributing to failure of a structure operating at high temperature. Structural integrity assessments of components operating at high temperature require an accurate prediction of the creep crack initiation. In general, assessments are based on experiments carried out using standard laboratory scale creep test specimens tested under either displacement or load controlled conditions. In practice, structures are subjected to combinations of residual and applied stresses which in turn lead to mixed boundary conditions. Conventional laboratory creep tests do not represent these circumstances. This dissertation considers the effects of elastic follow-up , long-range residual stress and applied load on creep crack initiation of Type 316H stainless steel. Novel test rigs are designed for the purpose of investigating. The concept of rig is based on a three bar structure with an initial misfit introduced into the central bar to represent a long range residual stress and could be characterised easily without using time consuming residual stress measurement techniques. Initial results demonstrated that the magnitude and the interaction of the residual stress with the applied loading is a function of the initial misfit displacements and the relative stiffness of the components of the system. Additionally, the subsequent behaviour of the system, with and without the application of additional loading, is governed by (a) the degree to which the misfit is accommodated by plastic and creep strain and (b) the elastic follow-up provided by the system.

Abstract The purpose of the thesis is to analyze the stability of inextensional/ extensional circular elastic rings under statically conservative and non-conservative forces. We assume that the beam is homogeneous and isotropic in material, linear in the constitutive law, and the type of Euler’s beam. The zero strain for the case where the natural axis of the beam is inextensible is considered as a constraint. We use Hamilton’s principle and the method of Lagrange multiplier to derive the dynamical equations of deformation or equilibrium equations. In finding the equilibrium solutions we solve the linear equilibrium equations first, then the nonlinear ones, and compare both results. For the inextensional case, we adopt the approximate method of Galerkin and Fredholm theorem to determine the critical load and position from the linear equilibrium equations. The nonlinear equilibrium equations of an inextensional beam is a nonlinear boundary value problem with Lagrange multiplier, their solution are not unique. We use some approximate method to discretize the continuous system and solve them to get the fundamental and secondary equilibrium paths and the intersection of these two paths is also called the point of bifurcation buckling. The bifurcation-buckling load can be determined by static analysis along the fundamental equilibrium path. For non-conservative system the stability for the bifurcation-buckling point and the points on the secondary equilibrium path can only be done by dynamical analysis with resource to the Liapunov stability definition. At the bifurcation-buckling point the linearized equation has zero-eigenvalue for its characteristic equation and therefore raises the zero-eigenvalue bifurcation problem .The equilibrium points on the secondary path raise the Hopf bifurcation problem due to the appearance of purely imaginary eigenvalues. For these two problems linear analysis is inconclusive, we have to include the nonlinear terms to render the stability problem solvable. We perform numerical integration of the nonlinear system to observe whether there exists finite-amplitude periodic oscillation(or limit cycle solution),that is, a solution without growing unboundedly, if it does, the system is said to be stable. As to the case of the beam with extensible natural axis, we can find out the exact solution for the linear equilibrium equation and extract the critical load and equilibrium position from it directly. We also use Galerkin method to discretize the nonlinear equilibrium equations and find the fundamental and secondary equilibrium paths by numerical method. The determination of the bifurcation-buckling point and the stability of the points on the secondary equilibrium path are of the same procedure as that for the inextensional case. The result shows that that bifurcation-buckling load of the extensible case is about four times by value of the inextensional one.

Slope instabilities have been affecting the grade slope of Provincial Trunk Highway 5 near the junction with Provincial Trunk Highway 10 in northwestern Manitoba for over 50 years. In recent years, the instabilities have resulted in significant damage to the highway pavement surface. In 2011, Manitoba Infrastructure and Transportation initiated a geotechnical investigation to gain a better understanding of the failure, identify possible failure mechanisms, and explore various remedial design alternatives in order to stabilize the slope. The site was instrumented with slope inclinometers and vibrating wire piezometers, and monitored over a period of two years. An extensive laboratory testing program was completed to compare the results of direct shear tests and torsional ring shear tests for determining the shear strength of the underlying Cretaceous clay shale. Measured values were compared with values back analyzed using limit equilibrium analysis. A coupled finite element model was used to model the expected excess porewater pressure response, and therefore the stability of the slope, during construction of a stabilization berm. It was subsequently calibrated to agree with the measured porewater pressure responses from the instrumentation. Finally, spring flood conditions were simulated to determine the effect of multiple flash flood events on the stability of the slope.

In this study, it is important the process of functional elastic composite yarn is developed and the mechanical properties of the yarn are investigated, and then the yarn will be used in daily commodities and industrial products. Core-spun elastic yarn was produced with spandex filaments and polyester or polyester/rayon staple fibers using a ring spinning frame and a multi-section drawing frame. Elastic wrapped yarn was manufactured with spandex filaments and textured nylon filaments using a rotor twister and the multi-section drawing frame. The results show that when the main drawing ratio of the spandex filaments is either 2.2 or 2.7, the maximum breaking tenacity and elongation of the core-spun elastic yarn are maximized. When the rotor speed is 4000-8000 rpm and the wrapping count of the textured nylon filaments is either 2.5 or 3.0 turns/cm, the maximum breaking tenacity of the elastic wrapped yarn with the spandex filaments of 78 dtex exceeds that of the yarn in any other processing conditions. However, when the rotor speed is 4000 rpm, the breaking tenacity trend of the elastic wrapped yarn with the spandex filaments of 940 dtex is not significant when the wrapping count increases. The maximum breaking tenacity of the elastic wrapped yarn increases with the increasing drawing ratio of the spandex filaments. As the wrapping count of the textured nylon filaments is 3.0-4.0 turns/cm, the drawing ratio of the spandex filaments is 2.0-3.5 and the rotor speed is 4000 rpm, the maximum breaking tenacity of the elastic wrapped yarn with the spandex filaments of 78 dtex is maximized. The elastic yarn is flexible and could be applied for pantyhose, underwear, jeans, sportswear, socks for medical use, bandages, girdles, warp-knitted fabrics, and so on.

This chapter describes elastic scattering events, where the wavelength of the scattered light is unchanged from that of the incident light and conservative scattering, scattering without absorption, sometimes closely approximated in clouds. The scattering regime, scattering versus wavelengths and scatterer size are introduced. Polarization in scattering is described by the Stokes vector and the polarization ellipse. Molecular (Rayleigh) scattering is presented and its atmospherically-important inelastic component, Raman scattering (the Ring effect) quantified. Mie scattering for spherical particles is described as is the commonly-used Henyey-Greenstein Mie phase function approximation. Non-spherical scatterers are introduced. The Ångstrom exponent and the expansion of phase functions in Legendre polynomials are described.

This book presents an in-depth deliberation on optical networks in four parts, capturing the past, present, and ensuing developments in the field. Part I has two chapters presenting an overview of optical networks and the enabling technologies. Part II has three chapters dealing with the single-wavelength optical networks: optical LANs/MANs, optical access networks using passive optical network architecture, SONET/SDH, optical transport network and resilient packet ring. Part III consists of four chapters on WDM-based optical networks, including WDM-based local/metropolitan networks (LANs/MANs) using single and multihop architectures over passive-star couplers, WDM/TWDM access networks as an extension of PONs with WDM transmission, WDM metro ring networks covering circuit-switched (using point-to-point WDM and wavelength-routed transmission) plus packet-switched architectures and WDM long-haul backbone networks presenting the offline and online design methodologies using wavelength-routed transmission. Part IV deals with some selected topics in six chapters. The first deals with transmission impairments and power-consumption issues in optical networks, while the next three chapters deal with the survivable optical networks, network control and management techniques, including GMPLS, ASON, and SDN/SDON, and datacenter networks using electrical, optical, and hybrid switching techniques. The final two chapters present elastic optical networks using flexible grid for better utilization of the optical-fiber spectrum and optical packet and burst-switched networks. The three appendices present the basics of the linear programming techniques, noise processes encountered in the optical communication systems, and the fundamentals of queuing theory and its applications in telecommunication networks.

AbstractThe paper deals with strategies for numerical compensation of thermo-mechanical deformation of machine tool spindles and the TCP, respectively. Methods for digital modelling and simulating the temperatures and thermo-elastic deformation are presented. This is done by considering the geometry, material data, drive signals and temperature values. The topic of compensating thermo-elastic effects in spindle units is an important topic in manufacturing. Analytical equation and function block methods for measuring and predicting thermal spindle growth are compared. The heat flow model converts variable spindle load, speed, coolant and ambient temperature into local temperatures followed by elastic deformations of the spindle unit. The simulation results were verified for different types of motor spindles by experiments on a spindle test rig at SPL GmbH. A thermal stiffness value [W/µm] is characterized by the energy losses of the spindle, which result in thermal growth. Different strategies for digital reduction of a thermal spindle growth were developed.

Abstract The Kirchoff-Love plate theory and electroelasticity theory are combined to formulate the computer aided design model for the trimorph ring actuators. An isotropic elastic ring is laminated between two identical piezoelectric rings to form the trimorph actuator. The inner surface of the actuator is fixed, and the outer surface is free or transversely load. The analytical solutions for the transverse displacement and the force distribution are derived. Numerical simulations for the transverse displacement under free and loaded boundary conditions are conducted. The maximum transverse displacements as functions of the geometry variables such as the thickness ratio and radius ratio are calculated and presented.

Under high pressure, the elastic deformation of floating ring seals has a significant influence on the seal leakage flowrate and rotordynamic coefficients. The present study establishes a coupled model of the clearance flow and elastic structure of floating rings with bulk flow model and finite element method. The results show that the structural deformation reduces the clearance thickness and decreases the leakage flowrate. On the other hand, the elastic deformation reduces the direct stiffness, and increases the cross-coupled damping and inertia coefficients. In addition, the deformation induces the cross-coupled stiffness and direct damping to increase rapidly with increasing eccentricity ratio. Generally, the structural deformation deteriorates the rotordynamic characteristics of floating ring seals. In order to alleviate the adverse influences, a deformation compensation method is presented and proved to be effective.

Thermal fatigue cracking has been observed for thick perforated spacer rings used as part of a thermal fatigue test loop operating at Bechtel Bettis, Inc. The perforated rings are used for instrumentation access to the fluid flow at the test specimen inlet and outlet, and are subject to alternating hot and cold forced flow, low oxygenated water every three minutes so that rapid changes in water temperature impart a thermal shock event to the inner wall of the rings. Thermal and structural three dimensional elastic and elastic-plastic finite element analyses (FEA) were conducted for the ring and the results used to predict fatigue crack initiation using strain-based fatigue-life algorithms. Predicted cycles-to-crack initiation agreed well with the observed cracking when alternating shear strain intensity analogous to the Tresca stress was used. This analysis qualifies the use of FEA for thermal fatigue assessments of complicated three-dimensional components.

<div class="section abstract"><div class="htmlview paragraph">Additive Manufacturing (AM) using stereolithography (SLA) was applied to produce engine O-rings using two different flexible polymer printing materials, Flex 80A and Elastic 50A. Print orientation of the O-ring in the SLA 3D printer is important, with the horizontal configuration most commonly providing for the smoothest final O-ring printed surface due to the lack of printing support tabs required. AM printing tabs lead to O-ring ‘marks’ (non-smooth surfaces) that were evaluated using the Society of Automotive Engineers SAE AS871B standard. It was seen that numerous printing approaches produced ‘marks’ that were larger than acceptable, which shows that these studied AM processes can not replace traditional methods of O-ring manufacture. However, further evaluation was pursued to explore possible remote emergency usage of these O-rings.</div><div class="htmlview paragraph">Printed O-rings were next tested-soaked in engine related fluids in order to characterize O-ring swelling behavior. Volume swelling was greatest with acetone (100% plus increase) for both the stock O-rings tested and moderately less so with the 3D printed O-rings. Flex 80A printing material swelling was moderately less than using Elastic 50A printing material. Swell testing using motor oil and engine fuels showed significantly less swelling with volume change increases on the order of ten to fifteen percent. Pressure vessel and engine-based testing was also performed with the printed O-rings demonstrating good performance (no leaks) under operation, suggesting that shorter term emergency-based operation using these AM printed O-rings may be acceptable.</div></div>

There is a concern that there may be areas of low toughness in the seam welds of submerged arc welded linepipe. These are typically associated with the Coarse Grained Heat Affected Zone (CGHAZ), and manifest themselves through low values obtained in Charpy impact and CTOD tests. Although this problem is not new, there has been renewed concern amongst linepipe users and manufacturers with the introduction of higher strength grades (X80 and upwards). A study was carried out using typical parameters for X70 and X100 grade material to investigate the structural performance of low toughness seam welds. Two-dimensional elastic T stress solutions for cracked flat strips can be used for constraint based analyses of long axial pipeline defects. Constraint based analysis has predicted the experimental ring tension results in X70 and X100 material with acceptable accuracy. Analysis of a range of surface breaking and buried defects has shown that low toughness levels in the HAZ are unlikely to adversely affect the integrity of high strength linepipe.
