LARGE STRAIN, ELASTIC-PLASTIC NUMERICAL ANALYSIS BY MEANS OF FINITE ELEMENT METHOD

Abstract

A method is presented for a large strain elastic-plastic analysis by the finite element method. The constitutive equations of elastic-plastic bodies can be obtained as the incremental relations between stress and strain. Thus, the finite element formulations result in the incremental relations between displacement and external load. In order to compute the incremental equations, several techniques hay to be introduced.
