Elastoplastic Large Deformation Using Meshless Integral Method
In this paper, the meshless integral method based on the regularized boundary integral equation [1] has been extended to analyze the large deformation of elastoplastic materials. The updated Lagrangian governing integral equation is obtained from the weak form of elastoplasticity based on Green-Naghdi’s theory over a local sub-domain, and the moving least-squares approximation is used for meshl...
متن کاملAn efficient large deformation method using domain decomposition
Efficiently simulating large deformations of flexible objects is a challenging problem in computer graphics. In this paper, we present a physically based approach to this problem, using the linear elasticity model and a finite elements method. To handle large deformations in the linear elasticity model, we exploit the domain decomposition method, based on the observation that each sub-domain un...
متن کاملDeformation Analysis of Perforated Sheets using Computational Homogenization
Introduction Perforated sheets are used in a number of industrial applications e.g. the shadow masks in colour monitor and television tubes. Their design requires the characterization of the deformation behaviour of a perforated sheet containing a large number of tiny holes. In practice, the holes are varying through the sheet thickness, however, in modelling this inhomogeneity is mostly ignore...
متن کاملInterfacial mixed-mode fracture of adhesive bonds undergoing large deformation
Interfacial fracture of adhesive bonds undergoing large-scale yielding is studied using a combined experimental/ finite-element approach. The full range of in-plane mode mixity is produced over bond thickness ranging from 30 to 500 lm using the scarf and the ENF joint geometries. Novel techniques for introducing pre-cracks and surface decoration, together with in situ observations, facilitate a...
متن کاملA Quasi-Static Method for Large Deformation Problems in Geomechanics
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...
