In shape memory alloys (SMAs), a precise determination of phase transformation surfaces around the crack tip, is very important for the prediction of fracture parameters. In this work, the size of phase transformation region surrounding the tip of a edge crack is evaluated analytically. The purpose is restricted to tip without and with curvature loaded in mode I.
