Elastoplastic material with isotropic damage

The two damage parameters needed to describe isotropic damage are shown to de_ne a damage domain and the evolution of damage is de_ned by a path within that domain[ Physical limitations on the path to full damage are developed[ A thermodynamically consistent set of constitutive equations with which the damage path can be evaluated is developed for a speci_c material[ 0887 Elsevier Science Ltd[ All rights reserved[
