Abstract
A multi-dimensional thermomechanical model has been developed to simulate the localized phase transformation and propagation of transformation front(s) in SMA materials. The current model is an extension of the one-dimensional model previously developed by the authors which consists of a constitutive relation and a transformation evolution rule (kinetic relation). The constitutive relation is constructed based on continuum mechanics principles, and the kinetic of transformation is expressed in terms of various transformation surfaces in stress-temperature space. The model captures the localized deformations in both forward and reverse transformation. The finite element simulation of the forward and reverse transformations in a short NiTi strip under quasi-static extension is presented.
