A transformation criterion that includes the effect of tension-compression asymmetry and texture-induced anisotropy is used to describe the size of the transformation region surrounding the tip of an edge crack in a shape memory alloy. This analysis is made within the framework of the linear elastic fracture mechanics (LEFM). Different opening modes are considered. Transformation surfaces obtained are compared with those published by Lexcellent et al. (Int. J. Fract. 169: 1-13, 2011) for the isotropic case to capture the influence of transformation anisotropy for different fracture modes.
