Abstract: A thermodynamics-based energy analysis approach for pressure-dependent materials is presented. Formulation of plastic free energy and plastic dissipation for the nonassociated Drucker-Prager plasticity model is derived ...

Abstract: Presented is a study on energy dissipation in dynamic inelastic systems due to material inelasticity, viscous damping, and algorithmic damping. Formulation for plastic dissipation is based on thermodynamics, with consideration ...
