Abstract
We propose a numerical model for the dynamics of the austenitic-martensitic transformation which includes the effect of surface energy. Our numerical model uses a nonconforming finite element method to approximate the deformation and a numerical viscosity to stabilize the scheme. We present numerical experiments which demonstrate that the addition of a strain-gradient surface energy results in a more planar austenitic-martensitic interfacial layer.
