Dynamic perfect plasticity as convex minimization Elisa Davoli, University of Vienna Abstract We present a novel approximation of solutions to the equations of dynamic linearized perfect plasticity, based on a global variational formulation of the problem by means of the Weighted-Inertia-DissipationEnergy (WIDE) approach. Solutions to the system of dynamic PrandtlReuss perfect plasticity are identified as limit of minimizers of parameterdependent energy functionals evaluated on trajectories (the WIDE functionals). Compactness is achieved by means of time-discretization, uniform energy estimate on minimizers of discretized WIDE-functionals, and passage to the limit in a parameter-dependent energy inequality. This is a joint work with Ulisse Stefanelli.
