Abstract: | Based on irreversible thermodynamics and internal state variable theory, the volume-averaged Clausius-Duhem inequality is
presented. In contrast to former investigations on damage-elastoplasticity, our evalustions are founded on the volume-averaged
field equations of the analyzed elements and the self-consistent method. Hence, our results not only include the influence
of void shapes but also consider the interaction among voids. Further, previous work about coupled elastoplastic damage problems
only takes into account small initial void volume fractions. Our work, however, will be able to deal with elastoplastic damage
problems with larger initial void volume fractions.
