Fatigue crack closure: A myth or a misconception? [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2019 AbstractIn this paper, we have extended our previous study on fatigue crack closure to examine the phenomenon of crack opening displacement (COD) and its impact on the crack tip fields in both 2D and 3D specimen geometries using full‐field experimental measurements and integrated finite element modelling.

Analysis of transformation-induced crack closure [PDF]
Engineering Fracture Mechanics, 1991 Abstract 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.

Role of plasticity-induced crack closure in fatigue crack growth [PDF]
Fracture and Structural Integrity, 2013 The premature contact of crack surfaces attributable to the near-tip plastic deformations under cyclic loading, which is commonly referred to as plasticity induced crack closure (PICC), has long been focused as supposedly controlling factor of fatigue ...
