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...

Constitutive modelling of hyperelastic rubber-like materials

The simulation of rubber-like material behaviour by means of the finite element method has been described in this study. Proper material models were selected for the numerical description of static hyper-elasticity. The combinations of a continuum damage mechanics concept and a pseudo-elastic concept with Gao’s elastic law were used to simulate the ideal Mullins effect. Furthermore, a specific ...

A comparative study on constitutive modeling of hot deformation flow curves in AZ91 magnesium alloy

Modeling the flow curves of materials at elevated temperatures is the first step in mathematical simulation of the hot deformation processes of them. In this work a comparative study was provided to examine the capability of three different constitutive equations in modeling the hot deformation flow curves of AZ91 magnesium alloy. For this, the Arrhenius equation with strain dependent constants...
