Effect of compressive loads on plasticity induced crack closure [PDF]
Theoretical and Applied Fracture Mechanics, 2015 Abstract Compressive stresses play an important role on tension–compression fatigue which can be attributed to plasticity induced crack closure (PICC). The objective here is to study numerically the effect of compressive stresses on PICC and to discuss the applicability of PICC to explain the effect of negative stress ratios on fatigue crack growth ...

Behavior of plasticity-induced crack closure and roughness-induced crack closure in aluminum alloy
International Journal of Fatigue, 2001Abstract 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, 2008ABSTRACTIn 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, 2019Abstract 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.

Modelling plasticity-induced fatigue crack closure
Engineering Fracture Mechanics, 1990Abstract A numerical analysis of plasticity-induced fatigue crack closure based upon the finite difference method is presented. This new method permits modelling easily fatigue crack growth as well as contacts between fracture faces, without requiring sophisticated algorithms.

Asymmetric crack wake plasticity – a reason for roughness induced crack closure
Acta Materialia, 2004Asymmetric arrangement of geometrically necessary dislocations in the wake of a crack tip induces a mismatch of fracture surfaces. It can explain the occurrence of the roughness induced crack closure far behind the fatigue crack tip. The asymmetric arrangement of geometrically necessary dislocations is verified by local crystal orientation measurements
