Existence and regularity of solutions for an evolution model of perfectly plastic plates
We continue the study of a dynamic evolution model for perfectly plastic
plates, recently derived from three-dimensional Prandtl-Reuss plasticity. We
extend the previous existence result by introducing non-zero external forces in
the model, and we discuss the regularity of the solutions thus obtained. In
particular, we show that the first derivatives with respect to space of the
stress tensor are locally square integrable
