Extension of the CJP model to mixed mode I and mode II [PDF]
Fracture and Structural Integrity, 2013 The present authors have previously proposed a novel ‘plastic inclusion’ approach for dealing with the local plasticity which occurs at the tip of a growing fatigue crack.

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 ...

Effect of crack propagation on crack tip fields [PDF]
Fracture and Structural Integrity, 2013 Crack closure influences fatigue crack growth rate and must be included in the design of components. Plasticity induced crack closure is intimately linked with the crack tip plastic deformation, which becomes residual as the crack propagates.

Crack tip strain evolution and crack closure during overload of a growing fatigue crack [PDF]
Fracture and Structural Integrity, 2017 It is generally accepted that fatigue crack growth is retarded after an overload, which has been explained either by plasticity-induced crack closure or near-tip residual stress.

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

Measurement and simulation of strain fields around crack tips under mixed-mode fatigue loading [PDF]
Fracture and Structural Integrity, 2015 For various configurations examined in a series of fatigue experiments on thin-walled tubes under tension and torsion, the experimental results – crack path, crack growth life, near crack tip deformations, and crack closure – are measured and compared to

A numerical study of non-linear crack tip parameters [PDF]
Fracture and Structural Integrity, 2015 Crack closure concept has been widely used to explain different issues of fatigue crack propagation. However, different authors have questioned the relevance of crack closure and have proposed alternative concepts. The main objective here is to check the

The Evaluation of Front Shapes of Through-the-Thickness Fatigue Cracks
Metals, 2021 Fatigue failure of structural components due to cyclic loading is a major concern for engineers. Although metal fatigue is a relatively old subject, current methods for the evaluation of fatigue crack growth and fatigue lifetime have several limitations.
