Title: Perfectly plastic heterogeneous materials


			 Guillermo Goldsztein


Abstract:
We consider heterogeneous materials with elastic-perfectly plastic pure
phases. Our goal is to evaluate the strength domains of these materials
(i.e. the set of stresses that these materials can withstand). We will
present our results on the two-dimensional problem that results if the
microstructures are compatible with the applied anti-plane deformations.
