Résumé / Abstract

In this Paper is introduced a time-discretization scheme for the numerical simulation of coupled thermomechanical evolutions of SMA structures. A particular feature of this time-discretized problem is that its solutions can be expressed as the solutions of a variational problem. This variational formulation allows one to study the existence and unicity of solutions. The approach presented is applied to simulate the propagation of a martensitic zone in a circular cylinder under traction
