Abstract
This paper presents the formulation of energy-dissipative momentum-conserving time-stepping algorithms for finite strain dynamic plasticity. These methods require special return mapping algorithms for the integration of the plastic evolution equations, as well as the proper assumed strain treatment to arrive at fully conserving, locking-free assumed strain B-bar finite element methods.
