Abstract
This paper describes an h-adaptive, space-time discontinuous Galerkin finite element method for quasi-static viscoplastic response in a time -varying domain. The equations of equilibrium and the evolution equati ons in the viscoplastic material model comprise an elliptic/hyperbolic system. We focus here on two aspects of the model: stabilization of t he hyperbolic subproblem and residual-based error estimates and adapti ve algorithms for viscoplastic analysis.
