The variational structure of classical plasticity
2018
Mathematics and Mechanics of Complex Systems
A unified approach to classical plasticity, including metal plasticity, geomaterials, and crystal plasticity, is presented. A distinctive feature of this approach is that the basic constitutive elements (yield criterion, flow rule, consistency condition, and hardening rule), instead of being assumed on a phenomenological basis or deduced from ad hoc principles, are obtained directly from the stationarity of the energy. The plastic continuum is regarded as a particular micromorphic continuum,
