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.

Plasticity induced crack closure in adhesively bonded joints under fatigue loading [PDF]
, 2015 The mean load of a cyclic loading has a large effect on fatigue crack growth rates in metallic materials and bonded joints. In metallic structures, this effect has been attributed to plasticity-induced crack closure, but little is known about the ...

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.
