Abstract:

ABSTRACT - We show that minimizers of elastic-plastic energies dependent on jump integrals are smooth provided a smallness condition is fulfilled by the load. We examine also the structure of extremals when this smallness condition is violated.

Keywords: calculus of variations, free discontinuity, Special Bounded Hessian , Elasto-Plasticity
