A unified variational framework and finite element simulations of phase transformation dynamics in a shape memory alloy thin film are reported in this paper. The computational model is based on an approach that combines the lattice-based kinetics involving the order variables and non equilibrium thermodynamics. Algorithmic and computational issues are discussed. Numerical results on phase nucleation under mechanical loading are reported.
