A derivation of a thermodynamic transformation criterion for the martensitic transformation from a f.c.c. to a b.c.t. lattice is presented in a continuum mechanical framework. The thermodynamic force at a point of an interface is determined and discussed in the light of earlier literature. Starting from this local thermodynamic force a global rate of energy balance is given. The integration of...
Either pure cooling induced martensitic transformation or pure stress assisted martensitic transformation in constrained zirconia in two materials with homogeneous (PSZ) and heterogeneous (ZTA) elastic and thermal properties is investigated by the finite element method. The morphology of the martensite (number of twin bands, relative thickness) determines the strain energy caused by the transformation...
