Development of Plasticity and Ductile Fracture Models Involving Three Stress Invariants

Published: Jan 1, 2012
Abstract
It has been shown that the plastic response of many materials, including some metallic alloys, depends on the stress state. Based on plasticity analysis of three metal alloys, a series of new plasticity models with stress state effect is proposed. The effect of stress state on plasticity and the general forms of the yield function and flow potential for isotropic materials are assumed to be functions of the first invariant of the stress tensor...
