Abstract

This paper presents a generalized constitutive model with a mixed strain hardening for implicit elastic/visco-plastic boundary element method, which includes both the isotropic and kinematic hardenings. As compared with the usual implicit scheme, in this implicit scheme, the viscoplastic strain rate contains not only the current stress increment but also the viscoplastic strain increment. Numerical example, discussion and comparison with existing research results are presented to illustrate the performance of the implicit algorithm 1. Introduction The elastic/viscoplastic material model which i
