Basic constitutive equation in multiplicative hyperelastic-based plasticity

Abstract

The exact formulation of the multiplicative hyperelastic-based plastic constitutive equation is given for the conventional elastoplastic constitutive equation with the yield surface enclosing the purely-elastic domain undergoing the isotropic and the kinematic hardenings in this article. The generalized flow rules for the plastic strain rate and the rate of kinematic hardening variable and their related plastic spins are incorporated in this formulation.
