Evaluation of overload effects on fatigue crack growth and closure [PDF]
Engineering Fracture Mechanics, 2003 Fatigue crack propagation tests with single tensile peak overloads have been performed in 6082-T6 aluminium alloy at several baseline [Delta]K levels and stress ratios of 0.05 and 0.25. The tests were carried out at constant [Delta]K conditions.

Measurement and simulation of crack growth rate and direction under non-proportional loadings [PDF]
Fracture and Structural Integrity, 2015 A series of fatigue experiments on thin-walled tubes under tension and torsion, the experimental results – crack path and crack growth life – are measured and compared. It is observed that the cracks follow a curvature from a tensile to a shear dominated

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 ...
