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.

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.

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.

Plasticity Induced Crack Closure under Plane Strain Conditions
Key Engineering Materials, 2011Plasticity Induced Crack Closure (PICC) is a main phenomenon affecting fatigue crack growth and must be included in the design of components. The objective of the present paper is to study the level of PICC under plane strain conditions. The numerical parameters were identified and optimized. The effects of load level and material model were studied.

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

Influence of through‐thickness crack shape on plasticity induced crack closure
Fatigue & Fracture of Engineering Materials & 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
