摘要：

Deformation-induced martensitic transformation around a fatigue crack results in the phenomenon of crack closure. By approximating the residual stress field due to the volume expansion in the transformed zone as that of an edge dislocation pair, a closed-form solution of crack opening as a function of external loading is derived. The result indicates that the exact determination of crack closure point by compliance measurement is inherently difficult.
