Fatigue & Fracture of Engineering Materials & Structures, 2018
AbstractIn the present work, comprehensive investigation of both theoretical analysis and numerical simulation was carried out to investigate the plastic mismatch effect on plasticity induced crack closure (PICC) behavior and effective fatigue crack tip driving force.

Fatigue Crack Growth at Notches Considering Plasticity Induced Closure
2008Classical fatigue analyses discriminate between technical crack initiation (crack length of about 1mm) and crack propagation stages. The stage of crack initiation, however, is itself dominated by the growth of short fatigue cracks. Based on the assumption that a fatigue life to initiate a microstructurally short crack of dimensions in the order of 10µm

Dislocation-based model of plasticity and roughness-induced crack closure
International Journal of Fatigue, 2013Abstract Along with external forces and the macro-geometry of cracked bodies, the local stress intensity factors Δk and kmax at fatigue crack fronts are also determined by internal stress fields and the crack front microgeometry (extrinsic shielding).

An Analytical Investigation of Plasticity Induced Closure Involving Short Cracks
1988Plasticity induced crack closure and its effect on the fatigue growth of short cracks is investigated numerically. A plane stress finite-element analysis is used to simulate a nonpropagating crack of length 65 μm in a single-edge-cracked specimen under two stress levels and two values of stress ratio R.

A BOUNDARY ELEMENT MODEL OF PLASTICITY‐INDUCED FATIGUE CRACK CLOSURE
Fatigue & Fracture of Engineering Materials & Structures, 1998This paper describes a plane stress boundary element model of plasticity‐induced fatigue crack closure. A simple Dugdale‐type strip yield zone is used and quadratic programming techniques are employed to establish crack shape, stress and plastic deformation.

A numerical analysis of the plastic wake influence on plasticity induced crack closure
2017Fatigue crack closure has been studied by means of finite element method since long time ago. Most work has been performed considering bi-dimensional models. Lately, the use of threedimensional models has been extended. Nevertheless, the methodology employed has been taken from that developed for bi-dimensional cases.
