It is well-known that plastic deformations in shape memory alloys stabilize the martensitic phase. Furthermore, the knowledge concerning the plastic state is crucial for a reliable sustainability analysis of construction parts. Numerical simulations serve as a promising tool for the realistic investigation of the complex interactions between phase transformations and plastic deformations. An implementation of an appropriate material model into commercial finite element programs, e.g. Abaqus, offers the opportunity to analyze entire structural components at low costs and fast computation times [1,2,3], The model employed is based on energetic quantities, i.e. temperature-dependent caloric energy and dissipation, which offers a rather universal applicability since it has to be calibrated only once for each alloy composition regarded [4].
