Formulation for Evolution Rule of Elastic-core in Subloading Surface Model

Abstract

The extended subloading surface model with the translation of the elastic-core is capable of describing rigorously the monotonic and the cyclic loading behaviors. The translation rule of the elastic-core is considered in this article. Here, the dissipative parts in the plastic strain rate for the internal variables are formulated, which is required in the multiplicative hyperelatic-based plastic constitutive equation.
