Abstract

A dual yield constitutive model involving both the J2-flow and a threshold-shear-stress based flow, described in the accompanying article, is incorporated in a finite element program, and a simulation of shear band localization occurring in a uniaxially loaded plane strain specimen is carried out. The FEM takes into account the finite strains and the rotations involved in the formation of the shear band. These numerical experiments not only validate the postulated constitutive equation, but also aid in investigating the effect of the material hardening exponent, the aspect ratio of the specimen, and the mesh morphology on the formation of the shear band.
