Displacive phase transformation occurs readily under stress-wave loading and is dependent on the nonhydrostatic stress state. Both static and stress-wave data for phase transformation in calcite rock are compared for shear stress dependence. A nonhydrostatic thrmodynamic theory has been developed. Through the theory, nonhydrostatic relations of phase equilibria are obtained which constrain the volume and shape change through the transformation. The theory is applied to the stress-induced displacive calcite I-II phase change in Oakhall limestone.
