Abstract:

We offer an alternate derivation for the symmetric-hyperbolic formulation of the equations of motion for a hyperelastic material with polyconvex stored energy. The derivation makes it clear that the expanded system is equivalent, for weak solutions, to the original system. We consider motions with variable as well as constant temperature. In addition, we present equivalent Eulerian equations of motion, which are also symmetric-hyperbolic.

Abstract:

Stop-motion animation is an ancient form of animation. After nearly a century of development, the material application of stop-motion animation becomes diversified. Currently, however, the well-known stop-motion animations are produced by clay materials. Clay materials play an important role in the application of stop-motion animation. Clay materials, because of its expressive ability demonstrated by its strong plasticity, enables the roles it has shaped lively and characteristic and the stop-motion animation to be full of affinity and vitality. This paper starts from the properties and material expressive ability of clay materials, combined with the short clay animation film named Daffodil to have a study and analysis of the vitality demonstrated by clay materials.

Full text

Abstract:

The kinematics of the deep rolling tool, contact stress, and induced residual stress in the near-surface material of a flat Ti-6Al-4V alloy plate are numerically investigated. The deep rolling tool is under multiaxis nonlinear motion in the process. Unlike available deep rolling simulations in the open literature, the roller motion investigated in this study includes penetrative and slightly translational motions. A three-dimensional finite element model with dynamic explicit technique is developed to simulate the instantaneous complex roller motions during the deep rolling process. The initial motion of the rollers followed by the penetration motion to apply the load and perform the deep rolling process, the load releasing, and material recovery steps is sequentially simulated. This model is able to capture the transient characteristics of the kinematics on the roller and contacts between the roller and the plate due to variations of roller motion. The predictions show that the magnitude of roller reaction force in the penetration direction starts to decrease with time when the roller motion changes to the deep rolling step and the residual stress distributions in the near-surface material after the material recovery step varies considerably along the roller path.

Abstract:

In order to get a profound understanding of planet motion and orbital motion in CCOS (Computer Controlled Optical Surfacing), a compare study between them was conducted here. The material removals of two motions under the same conditions were simulated and the removal of planet motion was higher than that of orbital motion. The figuring abilities of two motions were also studied through the theory of cut-off frequency and the result showed that planet motion had a higher cut-off frequency. Then two figuring runs which employ the planet motion and the orbital motion were simulated. The convergence rates and polishing times of these two runs were compared and the result showed that planet motion had a higher figuring efficiency. As planet motion has stronger figuring ability and higher figuring efficiency, it’s better to employ planet motion in CCOS to get higher convergence rate and higher accuracy when fabricating high quality mirrors.

Abstract:

Solid objects lying on slopes for which gravity alone would be insufficient to overcome frictional resistance have long been known to experience downslope motions when subject to alternations in temperature. This paper will suggest that similar motions are possible in situations where gravity is either absent or even working against the prospective motions. It will be argued that the effects of differential material properties when the solid is subject to alternations of tension and compression, accompanying periodic cycles of high and low temperatures, can also produce motion. While most of the illustrative examples will be chosen from certain movements of either ice and ice-rich materials or asphalt pavements, it would appear that similar behaviour could be experienced by much wider classes of materials. It is suggested that this form of thermal ratchet process could be of importance far wider than is currently recognized.

Abstract:

This article discusses a practical exploration of the ability of a textile to meet with and affect bodies. It buildson the inherent ability of textiles, particularly in the form of a garment, to evoke movements and emotions. This paper suggests a shift in focus of the design of bodily materiality, towards an expression emerging from interactions connecting materiality and performativity. The findings are the result of 2.5 years of exploration,during which four performances, ten workshops, and four exhibitions were performed. The entwined parameters of expressing and informing are applied as a material choreographic thinking, which in this case results in a material choreography of openness, where expressing and informing are essential as entwined design parameters in the design of body-material interactions. The material choreography is developed as a method for addressing somatic experience, with improvements in terms of wellbeing and presence as aesthetic goals, focusing on reducing movements and emotions relating to stress for people suffering from chronic fatiguesyndrome.

Abstract:

We are developing a passive power assist device, “Smart Suit Lite.” Smart Suit Lite is a compact, lightweight power assist device that utilizes the elastomeric force of elastic materials. We have developed a “motion-based assist method” in order to design Smart Suit Lite for particular motions. We have also developed an extended musculoskeletal model which has “Skin segments” that aid in analyzing assistive force. In this paper, we target the movements of caregivers. From three-dimensional motion data and an extended musculoskeletal model, we analyze human muscle forces and assistive forces. We then design the arrangement and properties of the elastic materials, based on the motion-based assist method. Finally, we verify its assistance effect through basic experiments.

Abstract:

Nonlinear dynamic behaviors of the fractional calculus model viscoelastic arch are discussed in this paper. The motion equations governing dynamic behaviors of the viscoelastic arch is derived and simplified by Galerkin method. The numerical method for solving the motion equations with fractional calculus is presented here. The influences of the load parameter and the material parameter are considered respectively. The results show that the chaotic vibration of the arch appears in forced vibration. And both the load parameter and the material parameter affect the dynamic behavior of the arch. With the increasing of the load parameter, the motion states changed from periodic motion with period 1 to complex motions, such as mult-periodicity, quasi-periodicity or chaos. The increasing of the material parameter benefits the stability of the structures.

Abstract:

The well-known transcistrans photoisomerization of azobenzenes produces at least three different kinds of motion in the polymer materials to which the azobenzenes are bound. The first is a photoinduced motion of the azobenzene groups only, and they can align in a selected position with respect to the light polarization. The second is a macroscopic motion of huge amounts of polymeric material, producing surface deformation, and the third is a reorganization of smectic domains in liquid crystalline polymers. These motions and their consequences are briefly discussed in relation to the polymer structure and some possible photonic applications are mentioned.Key words: photoinduced orientation, azobenzene polymers, surface gratings, photonics, thermochromism, photochromism, photorefractivity, photoinduced chirality and switching.

Abstract:

Objectives Various materials are used to construct splints for mid-diaphyseal tibial fracture stabilization. The objective of this study was to compare construct stiffness and inter-fragmentary bone motion when fibreglass (FG) or thermoplastic (TP) splints are applied to either the lateral or cranial aspect of the tibia in a mid-diaphyseal fracture model. Methods A coaptation bandage was applied to eight cadaveric canine pelvic limbs, with a custom-formed splint made of either FG or TP material applied to either the lateral or cranial aspect of the osteotomized tibia. Four-point bending tests were performed to evaluate construct stiffness and inter-fragmentary motion in both frontal and sagittal planes. Results For a given material, FG or TP, construct stiffness was not affected by splint location. Construct stiffness was significantly greater with cranial FG splints than with cranial TP splints (p < 0.05), but this difference was not significant when comparing splints applied laterally (p = 0.15). Inter-fragmentary motions in the sagittal and frontal planes were similar across splint types for cranial splints, but for lateral splints there was a 64% reduction in frontal plane motion when FG was used as the splint material (p = 0.03). Clinical Significance FG produces a stiffer construct, but the difference is not reflected in a reduction in inter-fragmentary motion. For lateral splints, FG splints are associated with reduced inter-fragmentary motion as compared with TP and may therefore have slight superiority for this application.

Abstract:

High strength steel sheets are increasingly used in automotive body parts with the aim of weight reduction, but their use urgently requires further improvement in sheet forming technology to overcome difficulties such as poor formability, dimensional inaccuracy, etc. On the other hand, servo press facilities are becoming increasingly used in industry and many attempts are being made to bring out their characteristic features for enhancing the formability of high strength steel sheets. Although some of these attempts have been successful in finding the advantages of servo presses for improving formability and dimensional accuracy, the mechanisms of such improvements have yet to be clarified in conjunction with the mechanical properties of the materials used. One of the most remarkable features of the servo press lies in its flexibility in slide motion control. It is thus effective to investigate the relevance of strain rate sensitivity of a material to the mechanism of improvement in formability enabled by the flexible slide motion of the servo press. However, very few studies have been carried out with material testing, material modeling, and numerical analyses combined with experimental verifications. In this study, Norton’s creep model was implemented in the FEM solver in order to take into account visco-elasto-plastic deformation including stress relaxation behavior. Parameters for the visco-elasto-plastic material model were identified through physical measurements and FEM simulations of uniaxial tension and crosshead displacement dwell tests, as shown in Fig. 1. The identified material model was applied to sheet forming simulations of an automotive body part and validity of the model was examined by comparing with stamping experiments using a servo press with a variety of slide motions. Numerical results with the identified material model showed the same tendency with respect to the slide motions as the experimental results. Stress relaxation behavior was found to be an important factor for improving formability enabled by modifying the slide motion.

AbstractAn overview of currently available, large-area, proper-motion catalogs is presented. These include the well-known catalogs based on historical Schmidt-telescope surveys as well as other projects that make use of observational material the primary purpose of which, from inception, was the determination of proper motions. The various catalogs are characterized and compared, with an emphasis on their limitations and their appropriateness for various astrophysical uses.In addition to allowing for the maintenance of a practical celestial reference system, absolute proper-motion surveys provide the raw material from which a better understanding of our Galaxy's structure and kinematics can be built. Several examples will be cited in which large proper-motion surveys are used to probe and describe the distinct stellar components that comprise our Milky Way Galaxy.

Full text

Abstract:

In the virtual choreography, “Fluente”, the human material body is no more solid as we see, but is fluid as we imagine. One can see motion flows through the material body, because all the fluid motions are consequent on the energy transmission. Furthermore, the energy transmission does not only exist on one individual, but also exist among groups gradually and continually underlain the energetic conservation. Dancers exercise their body everyday in the aim to discover and rehearse how the motion of the whole is duly evolved from their motor locus. The process by which motors provoke the whole motion is as mysterious as beautiful; therefore, the author realizes it in the virtual choreography, “Fluente”. “Fluente” does not aim to present the fluid motion of human body but to explore the “inner propagation” existing within the real material bones, muscles, and our imagination as well. It comes from the center source with the vital breathe to flow as well to propagate perpetually.

Abstract:

Tetragonal ferroelectric materials are polarized to induce the anisotropy necessary for the piezoelectric effect. This poling of the material is inherently an orientation process. Pole figure texture measurements of poling and cross-poling in a lead zirconate titanate Navy VI material show domain motion. The resulting axisymmetric and three-dimensional textures demonstrate the contribution of 90° domain motion to piezoelectricity. Cross-poling results in strong orientations with lower applied fields than in the initial poling steps.

Abstract:

Abstract Sensor-based sorting provides state-of-the-art solutions for sorting cohesive, granular materials. Typically, involved sensors, illumination, implementation of data analysis and other components are designed and chosen according to the sorting task at hand. A common property of conventional systems is the utilization of scanning sensors. However, the usage of area-scan cameras has recently been proposed. When observing objects at multiple time points, the corresponding paths can be reconstructed by using multiobject tracking. This in turn allows to accurately estimate the point in time and position at which any object will reach the separation stage of the optical sorter and hence contributes to decreasing the error in physical separation. In this paper, it is proposed to further exploit motion information for the purpose of material characterization. By deriving suitable features from the motion information, we show that high classification performance is obtained for an exemplary classification task. The approach therefore contributes towards decreasing the detection error of sorting systems.

The work purpose is to increase the productivity of bulk material separation by means of engineering process development based on fundamentally new engineering equipment in the form of spiral sieves, the novelty of which is confirmed by six patents for invention of the Russian Federation. In the work there was used a complex method of investigations. Analytical methods allowed offering dependences for the definition of bulk material longitudinal motion speed in spiral sieves. Experimental investigations were carried out in order to confirm analytical dependences. The analytical investigation of bulk material separation into fractions for the purpose of conditional model choice for its description is presented. A mathematical model choice is fulfilled. There is analyzed a model of continuous medium and that of a material particle. A mathematical model is developed to determine a speed of longitudinal motion of bulk material from charging to unloading. There is presented not only a circuit and an experimental plant created in metal version, but the results of experimental investigations of bulk medium motion parameters subject to spiral sieve design peculiarities are shown which presented a coincidence level high enough.

Full text

Abstract:

A cylindrical tool was applied for ultrasonic bonding of multi-layered copper foil and a copper sheet to prevent damage to the foil during bonding. The strength of the joints bonded with the cylindrical tool was comparable to that of the joints bonded with a conventional knurled tool. The effect of the cylindrical surface tool on bondability was investigated thorough relative motion behaviors between the tool surface and the bonding materials, as well as on bond microstructure evolution. The relative motion was visualized with in-situ observation using a high-speed camera and digital image correlation. At shorter bonding times, relative motions occurred at the bonding interfaces of the foil and the copper sheet. Thereafter, the relative motion between the tool and the bonding material became predominant owing to bond formation at the bonding interface, resulting in a macroscopic plastic flow in the bonded region. This relative motion damaged the foil in knurled tool bonding, and the cylindrical tool achieved bonding without any damage.

Abstract:

Wear is defined as the process of destruction of the shallow layer of a coupling in a small volume of material, that leads to the wear particle occurence. The mechanism of wear particle formation depends to a great extent on the strain state in the contact area (elastic, plastic, elasto-plastic), on the nature of the material (breaking tenssion, flowing tenssion etc) and on the working conditions (pressure, velocity, temperature etc). The harder material, function on the maximum strain on the friction surface, function on the angle and the geometry of roughness (or abrasive particles) may be elastically or plastically distorted, thus changing the state of the conjugate surface.The paper proposes an answer mode analysis of the materials of a friction coupling with sliding motion, for materials with different hardness.

Abstract:

The main goal of our research is to find the connection between micro particles and microorganisms motion in the Nature, considered as Brownian’s Motion within the fractal’s nature. For ceramics and generally material science it is important to clarify the particles motion and other phenomena, especially for grains and pores. Our idea is to establish control over the relation order–disorder on particle motion and their collision effects by Brownian motion phenomena in the frame of fractal nature matter. We performed some experiments and got interesting results based on microorganism motion initiated by different outer energetic impulses. This is practically the idea of biomimetic correlation between particles and microorganisms Worlds, what is very original and leads towards biunivocal different phenomena’s understanding. Another idea is to establish some controlling effects for electro ceramic particle motion in chemical-materials sciences consolidation by some phenomena in the nature. These important research directions open new frontiers with very specific reflections for future of microelectronics materials.

Abstract:

An unstructured moving grid scheme is applied to track the real-time motion state of the material interface with large-scale deformation induced by shock in the compressible multi-material flow. The material interface is denoted as a special internal boundary which is made up of unstructured grid edges, and on both sides of that there exist grids used for the two different materials. Riemann problem is solved in order to track the motion of the grid points on the material interface, and the local re-meshing technique is also applied to cope with the large-scale deformation of the moving grids near the interface, especially for the case of strong shocks existing in the multi-material flows. Simultaneously, the material interface is also defined as a kind of grid-deforming boundary in case grid volumes are negative. To obtain the resolution of the whole multi-material flow domain, the arbitrary Lagrangian-Eulerian (ALE) is discretized using Harten-Lax-van Leer-Contact (HLLC) scheme. Several numerical calculations from shock-interface examples demonstrate that this moving grid technique is feasible and effective in tracking the real-time motion state of the material interface.

Abstract:

The feasibility of a newly proposed method for the removal of cutter marks in die finishing operations has been investigated. The method is based on the superposition of a tertiary motion onto the conventional cutter motions. Path equations that consider motion and geometric variables have been derived and used as a basis for the development of a computer simulation model for generating three-dimensional surface representations. It has been shown that the tertiary motion results in a considerable reduction in the volume of the material in the scallops or blend marks left on the surface.

Abstract:

AbstractIn a series of three articles, fundamentals of a vector form intrinsic finite element procedure (VFIFE) are summarized. The procedure is designed to calculate motions of a system of rigid and deformable bodies. The motion may include large rigid body motions and large geometrical changes. Newton's law, or a work principle, for particle is assumed to derive the governing equations of motion. They are obtained by using a set of deformation coordinates for the description of kinematics. A convected material frame approach is proposed to handle very large deformations. Numerical results are calculated by using an explicit algorithm. In the first article, using the plane frame element as an example, basic procedures are described. In the accompanied articles, plane solid elements, convected material frame procedures and numerical results of patch tests are given.

Abstract:

The paper presents a new adequate look on the character of motion of any material body, such as moving vehicle. It has been proved, that motion of material bodies has a quantum character. Due to this their consecutive energetic states are obtained by a jump. The phenomenon of quantum in the reference to vehicle kinetics has been derived by indicating its place on the background of characteristics of whole mechanics. The length of vehicle way in particular phases of its motion is that source characteristics the derivatives of which form the development of motion description of a material solid/body. It has been indicated that the quantum nature of body motion does not depend on its magnitude. Thus, as has been noticed, there is an analogy between the macro-body motion and electron motion which change its energy also by jump, by getting from one orbit (energetic level) to another.

Abstract:

Aim. The article deals with developing software to simulate the motion of an object with the given parameters of initial and final phase status. Materials and methods. A motion error in sports exercise is the result of kinematic deviation from the parameters of a given motion program. The mathematical apparatus of adaptive control allows neutralizing motion mistakes between a program and a real trajectory. It is based on utilising the information about current parameters of a phase status of a moving object in a mathematical structure of the control function. The article proposes and experimentally proves the hypothesis about the computer synthesis of motions in biomechanical systems based on the mathematical apparatus of adaptive control. In the computational experiments, a mathematical description of an object is based on a well-established law of open-time approximation (A.P. Batenko, 1977), which requires that both velocity and coordinates simultaneously take the given values. Motion time in this law is an uncontrolled parameter. The mathematical model of a moving object is built as a system of a first-order differential equation. Results. A mathematical model describing the motion of a material point with given phase coordinates at the initial and final points in time is implemented in a computer program. The program works based on the integrated development environment Visual Studio Express 2013 and the Visual Basic 2010 language environment. Conclusion. The developed computer model of adaptive control achieves the aim of any motion, which implies transferring an object from a given initial state to the required final state.

Abstract:

Process parameter conditions such as vibrating motion, abrasives, pressure and tool wear play an important role in vibration-assisted polishing of micro-optic molds as they strongly affect material removal efficiency and stability. This paper presents an analytical and experimental investigation on the effects of process parameters, aimed at clarifying interrelations between material removal and process parameters which affect polishing quantitatively. The material removal rate (MRR) and surface roughness which represent the polishing characteristics were examined under different vibrating motions, grain sizes of abrasives and polishing pressure. The effects of pressure and tool wear conditions on tool influence function were analyzed. The results showed that 2D vibrating motion generated better surface roughness with higher material removal efficiency while a smaller grain size of abrasives created better surface roughness but lower material removal efficiency. MRR gradually decreases with the increase of polishing pressure when it exceeds 345 kPa, and it was greatly affected by the wear of polisher when wear diameter on the polisher’s head exceeds 300 μm.

Abstract:

An analysis on the nonlinear forced vibration of thermally loaded FGM plate with two simply supported opposite and two free edges subjected to the in-plane and transversal excitations is presented. The material properties of the FGM plates are assumed to be temperature dependent and change continuously throughout the thickness of the plate, according to the volume fraction of the constituent materials based on the power law function. The temperature is assumed to be constant in the plane and varied only in the thickness direction of the plate. The plate is modeled by using the Von Karman hypothesis and the equations of motion are obtained by using an energy approach. It is our aim to choose a suitable mode function to satisfy the first two modes of transverse nonlinear oscillations and the boundary conditions for the FGM rectangular plates with two simply supported opposite and two free edges. The equations of motion can be reduced into a two-degree-of-freedom nonlinear system of transverse motion under combined thermal and external excitations by using the Galerkin's method. By the numerical method, the nonlinear dynamical equations are analyzed to find the nonlinear responses of the FGM plate with two simply supported opposite and two free edges. Under certain conditions the periodic motions and the chaotic motions of the FGM plate are found. The bifurcation diagram demonstrates that for a certain geometric and material properties the chaotic responses of the plate exist as the transverse excitation changes. Moreover, numerical simulations also illustrate that the deflections of the nonlinear dynamic of the FGM rectangular plate are larger than that of the periodic motions.
