Simulation of anisotropic dilation behaviour of layered and banded steel samples during phase changes

We consider anisotropic distortions due to solid–solid phase transformations during heat treatment of a layered or banded material which exhibits transformation-induced plasticity. These anisotropic macroscopic effects are due to the local microstructure orientation on a mesoscopic scale. We present numerical simulations for different types of microstructure and their effect on macroscopically observable deformations.
