Title: Quasi-Static Brittle Damage Evolution with Multiple Damaged Elastic States

Abstract: We present a variational model for the quasi-static evolution of brutal brittle damage for geometrically-linear elastic materials. We allow for multiple damaged states. Moreover, unlike current formulations, the materials are allowed to be anisotropic and the deformations are not restricted to anti-plane shear. The model can be formulated either energetically or through a strain threshold. We explore the relationship between these formulations. This is joint work with Christopher Larsen, Worcester Polytechnic Institute.
