Existence and linearization for the Souza-Auricchio model at finite strains

We address the analysis of the Souza-Auricchio model for shapememory alloys in the finite-strain setting. The model is formulated in variational terms and the existence of quasistatic evolutions is obtained within the classical frame of energetic solvability. The finite-strain model is proved to converge to its small-strain counterpart for small deformations via a variational convergence argument.
