Constitutive Analysis of Large Elasto- Plastic Deformation Based on the Multiplicative Decomposition of Deformation Gradient
Abstract-By using Lee’s (1969. 1. Appf. hfech. 36, l-6) multiplicative decomposition of the deformation gradient into its elastic and plastic part of Hill and Rice’s (1973. SlAbf J. Appf. Math. U, 44S-461) constitutive framework. explicit and consistent constitutive analysis of large clastoplastic deformation is given. Both isotropic and anisotropic material behaviour is considered. so that som...

متن کاملReal-time simulation of large elasto-plastic deformation with shape matching
Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until now, they are limited to scenarios with relatively small plastic deformation. In this work, we present a method for simulating deformable solids undergoing large plastic deform...
متن کاملShape Optimization of Elasto-plastic Structures with Shakedown Constraints
An integrated approach for all necessary variations within direct analysis, variational design sensitivity analysis and shakedown analysis based on Melan’s static shakedown theorem for linear unlimited kinematic hardening material behavior is formulated. Remarks on the computer implementation and numerical examples show the efficiency of the proposed formulation. Important effects of shakedown ...
متن کاملSome Computational Issues in Large Strain Elasto-plastic Analysis
The stress integration procedure proposed by Eterovic and Bathe [Inr. J. numer. Merh. Engng 30, 1099-l 114 (1990).] is studied in detail. The elasto-plasticity formulation is based on the use of the total logarithmic strains and Cauchy stresses, and the Euler backward method of time integration. The accuracy of the procedure is assessed in the solution of various analysis problems and is compar...
