Abstract

We study the asymptotic behavior of a variational model for damaged elastoplastic materials in the case of antiplane shear. The energy functionals we consider depend on a small parameter " , which forces damage concentration on regions of codimension one. We determine the 􀀀-limit as " tends to zero and show that it contains an energy term involving the crack opening.
