Closure Effect of I + II Mixed-mode Crack for EA4T Axle Steel
Chinese Journal of Mechanical EngineeringThe crack-closure effect is a crucial factor that affects the crack growth rate and should be considered in simulation analysis and testing. A mixed-mode I + II loading fatigue crack growth test was performed using EA4T axle steel specimens.

Plasticity induced crack closure: a sensitivity analysis [PDF]
, 2012 Plasticity induced crack closure (PICC) is closely linked to the monotonic and reversed plastic deformation occurring at the crack tip. The objective of the paper is to identify the different physical and numerical parameters affecting PICC, and ...

Partial crack closure under block loading [PDF]
, 1980 Fatigue crack propagation tests under high-low and low-high block loading sequences have been performed in aluminium alloy specimens. The tests were carried out at constant [Delta]K conditions. Two stress ratios were analysed: R = 0.05 and R = 0.4. Crack

Evaluation of overload effects on fatigue crack growth and closure [PDF]
, 2003 Fatigue crack propagation tests with single tensile peak overloads have been performed in 6082-T6 aluminium alloy at several baseline [Delta]K levels and stress ratios of 0.05 and 0.25. The tests were carried out at constant [Delta]K conditions.

Numerical Simulation of the Effect of Pre-Strain on Fatigue Crack Growth in AA2024-T351
MetalsThe objective here is to study the effect of pre-strain on fatigue crack growth (FCG) in 2024-T351 aluminum alloy. Three pre-strain conditions were considered: without pre-strain, compressive and tensile permanent pre-strains of 4%.

Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures
MATEC Web of Conferences, 2018 The well-known load frequency effect on creep-fatigue crack growth is explained by the interactions between fatigue and creep loading and is quantified using the concept of plasticity-induced crack closure.
