Abstract:

We continue the study of a dynamic evolution model for perfectly plastic plates, recently derived in MM from three-dimensional Prandtl-Reuss plasticity. We extend the previous existence result by introducing non-zero horizontal 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.
