Special Session 31: Variational energy and entropy approaches in non-smooth thermomechanics
Contents
I will discuss the opportunity of reformulating the celebrated Souza-Auricchio phenomenological model for shape-memory alloys within the GENERIC variational frame. In particular, the thermomechanical evolution of the medium is rephrased as a generalized gradient flow of its entropy. This variational structure can be efficiently exploited in connection with approximations. I will comment of this perspective both from the theoretical and the numerical viewpoint.
