Abstract

We consider the special case of doubly nonlinear differential inclusions which are rate independent. The new feature is that the dissipation potential depends not only on the rate but also on the state itself. The energy potential is assumed to be uniformly convex. This corresponds to evolutionary quasivariational inequalities where the constraint set depends on the state itself. A priori estimates are obtained using a special convexity condition for the sum of the energy potential and the directional derivative of the dissipation potential. Using this, an existence result is derived under the additional assumption that the dissipation potential satisfies certain weak continuity properties. Our uniqueness result generalizes previous of [MT04,BKS04] relies on differentiability conditions and a one-sided Lipschitz estimate, also called structure condition in [MT04].
