A revision of results for standard models in elasto-perfect-plasticity theory
This article revolves around the theory of elasto-plasticity, in particular, the Hencky model and the Prandtl-Reuss model subjected to the von Mises condition. All estimates are proven for an approximative problem, the Perčina-Mises model. The integrability of the displacement and the velocity are improved. Moreover, the authors show the BMO estimates for the stress and the Morrey-like estimates for the plastic strain. These lead to a sharper identification of the plastic strain than that known up to date.
