The developed method of stress fields in system "semiinfinite crosssection shear crack - mechanical lentiform twin" in single crystal Ni2MnGa in case of a postdeformation state at equal zero value to the exterior loading, which has to become the reason appearance of crack and the twin. Being based on the analys of the received results, are shown the features of distribution of pressure close to the sources of their formation, and also are revealed the areas of localisation of the greatest pressure.
