Abstract

Continuum Damage Mechanics deals with elastic or inelastic materials which undergo structural weakening as a result of micro-crack formation or micro-voids growth. In this study, a relevant mathematical model is developed in the context of Continuum Damage Mechanics. This mathematical model represents mechanical behavior of an elastic media which have micro-voids and which is subjected to a mechanical loading. As a result, constitutive equations for the stress and strain-energy density release rate are presented for the media under consideration. © 2006 Asian Network for Scientific Information.
