An efficient implementation for a model of martensite reorientation in martensitic shape memory alloys under multiaxial nonproportional loading

► We present a model for martensite reorientation based on the ZM model for SMAs. ► The model is implemented in a user material subroutine for use with Abaqus. ► A closed form expression for the material jacobian is given. ► Detailed derivation of the time-discrete equations is provided.
