A New Anisotropic Damage Model for Ceramic Matrix Composites

Within the framework of irreversible thermodynamics, a new general constitutive model for describing damage and its effect on the overall properties of anisotropic solids is proposed. The ability of the model to describe the overall stress-strain response as well as the loss of symmetry resulting from the interaction between initial and damage-induced anisotropy in a brittle matrix composite is demonstrated.Copyright © 2004 by ASME
