Major player among functional materials, Shape Memory Alloys (SMA) may undergo verylarge reversible strain. SMA exhibit a Martensitic Phase Transformation (MPT) when they aresubmitted to mechanical or thermal actions, and that gives them some specific characteristics.The thermomechanical behavior of SMA is now well controlled. However, the knowledge of theSMA fracture behavior is a major challenge for their design and sizing for their sustainableindustrialization. This research project has focused on the understanding, describing and quantifyingof the phenomenon of localization at the crack tip due to stress-induced MPT. The study includestwo main aspects: the development of an analytical model and its experimental correlation bysimultaneou...
