Micro Abstract:
A new framework for the simulation of shape memory alloys (SMA) and TRIP steels undergoing martensite-austenite phase transformations is introduced. The goal is the derivation and elaboration of a generalised model which facilitates the reflection of the characteristic macroscopic behaviour of SMA as well as of TRIP steels. The model is implemented in a micro-sphere formulation in order to capture polycrystalline behaviour and to simulate three-dimensional boundary value problems.
