Abstract

In this contribution we present a finite deformation material model for SMA which includes the effect of pseudoelasticity. The model is implemented into a FE code by using an innovative implicit time integration scheme. The final aim of the research work is to investigate whether FE simulations of SMA applications, e.g. NiTI-stents or medical foot staples, should be based on large strain formulations as the transformation strain during the phase transition can reach up to 10 %. If such a large strain model was not necessary the computational cost of the numerical investigations could be reduced significantly.
