A parameter for quantitative analysis of plasticity induced crack closure [PDF]
International Journal of Fatigue, 2015 Abstract Numerical models have been successfully developed to predict plasticity induced crack closure (PICC). However, despite the large research effort a full understanding of the links between physical parameters, residual plastic wake and PICC has not been achieved yet.

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 ...

An analytical model of plasticity induced crack closure
Procedia Engineering, 2010 AbstractAccurate and non-conservative measurements of fatigue crack growth rate are essential when designing efficient structures to be subjected to cyclic loading. Crack closure is a main mechanism of fatigue crack propagation and must be included.

Experimental evaluation of CTOD in constant amplitude fatigue crack growth from crack tip displacement fields [PDF]
Fracture and Structural Integrity, 2017 In the current work an experimental study of the crack tip opening displacement (CTOD) is performed to evaluate the ability of this parameter to characterise fatigue crack growth.

Growth of inclined fatigue cracks using the biaxial CJP model [PDF]
Fracture and Structural Integrity, 2015 The CJP model of crack tip stresses is a modified version of the Williams crack tip stress field which takes account of simplified stress distributions that arise from the presence of a zone of plastic deformation associated with the crack flanks and ...

Can Keff be assumed as the driving force for fatigue crack growth? [PDF]
Fracture and Structural Integrity, 2015 This work raises some new questions about the validity of blindly assuming that Elber’s effective stress intensity factor is the actual fatigue crack driving force, and that as so it can be used to explain all load sequence effects on fatigue crack ...
