Abstract

We study systems of conservation laws with convex inequality constraints. We analyze shock solutions for the underlying nonconservative system of partial differential equations. Then we study a model elastoplastic system of partial differential equations in the context of hypoelasticity. We show that a sonic point is necessary to construct a compression solution that begins at a constrained compressed state.
