Abstract Scope Unique properties of shape memory alloys (SMAs) has roots in the phase transformation between austenite and martensite, under applied mechanical load and/or temperature variations. Most of the experimental studies on fracture of SMAs are based on the premise of linear elastic fracture mechanics (LEFM) despite the fact that the tests do not comply with the small-scale yielding assumption. Considering the nonlinearities in the SMA response, a methodology is proposed for measuring the fracture toughness of SMAs using the J-integral criterion. The methodology relies on the ASTM standard E1820 modified to accommodate the Young's moduli mismatch between different phases. Finite element analysis (FEA) is employed to validate the methodology and fracture experiments are carried out using NiTi compact tension (CT) specimens. The experimental data are interpreted according to the proposed approach and J-integral fracture toughness is provided.
