Plasticity models and nonlinear semigroups
The authors investigate an initial boundary value problem for an elastic-plastic material modeled by a constitutive law for which the hysteretic dependence between stress and strain is described by a system of variational inequalities. The problem is posed as an evolution equation in a Hilbert space. For this equation there is proved the existence and uniqueness theorem for weak, strong and regular solutions.
