Behavior of plasticity-induced crack closure and roughness-induced crack closure in aluminum alloy

International Journal of Fatigue, 2001
Abstract For center-cracked tension specimens subjected to constant amplitude loading, fatigue crack closure and crack growth behavior in an aluminum alloy 7050-T7451 were investigated. The specimens were tested with stress ratios of −1.0, 0.0, 0.1 and 0.3 under constant amplitude loading.

Influence of through‐thickness crack shape on plasticity induced crack closure

Fatigue and Fracture of Engineering Materials and Structures, 2008
ABSTRACTIn most of the previous three‐dimensional (3D) numerical studies of plasticity induced crack closure (PICC), ideal shapes have been assumed for the cracks. The aim of present paper is to study the effect of crack shape on PICC. With this objective a 3D numerical model was developed to predict PICC in middle‐tension (MT) specimens with different

Strategy of plasticity induced crack closure numerical evaluation

Theoretical and Applied Fracture Mechanics, 2019
Abstract A propagating fatigue crack may be partly retarded thanks to a phenomenon called fatigue crack closure. The ability to accurately describe this phenomenon is of interest for the scientific and engineering community, because of its significant impact on the fatigue crack propagation rate.

Estimation of plasticity-induced crack closure in a pre-existing plastic zone

International Journal of Fatigue, 1996
Abstract To estimate the plasticity-induced crack closure in a pre-existing plastic zone using Newman's strip-yield model, the interactions between the crack plasticity and the pre-existing plasticity must be known. In the current study, the total plasticity of a fatigue crack propagating in a pre-existing overload plastic zone and a notch plastic ...

A numerical study of fatigue crack closure induced by plasticity

Fatigue and Fracture of Engineering Materials and Structures, 2004
ABSTRACTCrack closure delays the intrinsic mechanisms responsible for crack growth, therefore, it must be considered in fatigue crack growth modelling. The objective of this work is to develop a numerical procedure to predict crack closure induced by plasticity.

Numerical simulation of fatigue plasticity-induced crack closure for through cracks with curved fronts

Engineering Fracture Mechanics, 2016
Abstract The plasticity-induced crack closure of through-thickness cracks, in CT specimens of 304L austenitic stainless steel, is numerically simulated using finite elements. Crack propagation is achieved through node releasing, by applying constant Δ K amplitude, so as to limit the loading history influence.
