In this contribution, we present a constitutive model for shape memory alloys formulated within the generalized standard materials framework. It provides substantial flexibility for the development of constitutive equations. On the other hand, finding the optimal numerical solution procedure for the resulting systems of evolutionary inclusions can be challenging. We present our approach and illustrate the capabilities of the model on several numerical simulations compared with experiments.
