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.
