Non affine deformations and shape recovery in solids undergoing martensitic transformations
arXiv:0803.2270 · doi:10.1088/1742-5468/2008/06/P06003
Abstract
We study, using molecular dynamics simulations, the kinetics of shape recovery in a model solid undergoing transformations from square to a general rhombic lattice, the triangular lattice being included as a special case. We determine the necessary and sufficient conditions for such shape recovery in terms of the nature and dynamics of transient and localized {\em non-affine zones} which inevitably accompany the transformation.
