Real-time simulation and animation of 3D global deformations is the bottleneck of many applications, such as surgical simulator. In this paper, we present a system that simulates physically realistic large deformations of soft objects in real-time. We achieve the physical realism by modeling the global deformation using geometrically nonlinear finite element methods. We achieve real-time dynami...

Non-classical, "structured deformations" are used to describe microslip and to refine both balance laws and constitutive relations. The main tools employed are identification relations that link the ingredients in structui'ed deformations to geometrical changes at small length scales.

A basic mathematical model of the deformation a large elastic element small spacecraft in its plane is constructed. Deformations are caused by temperature shock after leaves Earth’s shadow on solar portion orbit. The used to conduct computational experiment with aim assessing perturbations acting due shock. distribution during thermal described one-dimensional conductivity. classical theory thi...

It is well accepted that soft tissue deformation a combination of linear and nonlinear response. During small displacements, tissues deform linearly while during large show deformation. This paper presents new approach for modelling deformation, from the standpoint Mass Spring Method (MSM). The proposed MSM model developed using conical spring methodology which allow to have different stiffness...

based on two-dimensional plane stress and bifurcation functional from hill's general theory in polar coordinate the critical condition for elastic wrinkling of the flange of a circular blank ( the wave number in the flange and wrinkled area) during the deep-drawing process are obtained analyticaly to improve the previous given results. in this analytical study, the elastic limitation of the mat...

Abstract The application of reprocessable and reprogrammable soft actuators is limited by the synthetic strategies, 3D‐shaping capabilities, small deformations. In this work, melt‐processable supramolecular based on segmented copolymers containing thiourethane liquid crystal segments have been prepared via sequential thiol addition reactions in a one‐pot approach using commercially available bu...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...
