Notes:
In this study, the simulation of the motion of an interface during the stress-inducedmartensitic transformation of a shape memory alloy is performed using the level-set method. Thekinetics of the phase transformation is defined as an anisotropic kinetic relation between the rate atwhich the weak discontinuity moves, given by its normal velocity, and the thermodynamics drivingforce. The latter is derived from a dissipation function, which obeys the 1st and 2nd law ofthermodynamics and accounts for large strains. Furthermore, a hyperelastic constitutive framework isused to describe the constitutive behavior of the material. The model is implemented into the finiteelement method and is then used to solve a 2D phase transformation problem in a shape memoryalloy
