Abstract:
We present a novel variational approach to dynamic perfect plasticity. This is based on minimizing over entire trajectories parameter-dependent convex functionals of Weighted-Inertia-Dissipation-Energy (WIDE) type. Solutions to the system of dynamic perfect plasticity are recovered as limit of minimizing trajectories are the parameter goes to zero. The crucial compactness is achieved by means of a time-discretization and a variational convergence argument.
