- Description
- Starting from rigid-plasticity, we develop variational formulations of first incremental elastoplasticity and then elastoplastodynamics. These formulations are discretized using standard finite element techniques which results in discrete optimization problems that can be solved efficiently by modern mathematical programming methods. Finally, the extension from associated perfect plasticity to general nonassociated and hardening plasticity is detailed.
