As the basis of carrying guide rail operation, beam support mode has been widely used in high-end manufacturing, equipment, mechanical engineering and other fields. With rotating structure driving position attitude changes, flexible three-dimensional space movement can be realized.The key technology to drive branch is control deformation rail. The mainly affects structure, stiffness, supporting...

Electrokinetics-induced motion and deformation of a hyperelastic particle confined in a slit microchannel has been numerically investigated for the first time with a full consideration of the fluid-particle-electric field interactions and the dielectrophoretic (DEP) effect. When the initial orientation of a cylindrical particle with respect to the applied electric field, θ(p0), is 90°, the part...

The time dependent Ginzburg-Landau (TDGL) equation is a typical model in phase field theory for many applications like two phase flow simulations and phase transitions. In this paper, we develop effective algorithms so that the solution of the TDGL model can be accurately approximated. Specifically, we adopt finite element methods for the spatial discretization and study different algorithms fo...

Non-rigid registration becomes more and more important in biomedical imaging applications. A novel non-rigid registration method based on diffusion model with demons algorithm is proposed in this paper. The moving image is considered as a deformable grid, and it is diffusing through the contours of the objects in itself, by the action of effectors, called demons, situated in these interfaces. I...

The Finite Element Method (FEM) has become the standard tool for the analysis of a wide range of mechanical problems. However, the classical FEM is not well suited for the treatment of large deformation problems since excessive mesh distortions require remeshing. The Material Point Method (MPM) represents an approach in which material points moving through a fixed finite element grid are used t...

Abstract-Transonic interfacial crack growth in bimaterial systems is analysed, and the asymptotic field around the moving crack tip is obtained by the straightforward approach of analytic continuation. The power of singularity is less than l/2 for anti-plane shear deformation. For in-plane deformation, the power of singularity can be real or complex, depending on the speed of the crack tip. Acr...

Abstract. We study a moving boundary value problem consisting of a viscous incompressible fluid moving and interacting with a nonlinear elastic fluid shell. The fluid motion is governed by the Navier-Stokes equations, while the fluid shell is modeled by a bending energy which extremizes the Willmore functional and a membrane energy that extremizes the surface area of the shell. The fluid flow a...

The principal effects of plastic deformation on the low-temperature conductivity of alkali halide crystals are summarised and interpreted as follows : 1. The high conductivity during deformation is due to the movement of charged dislocations under the forces exerted simultaneously by the stress and the applied electric field. 2. The increased conductivity following deformation which subsequentl...
