A Review on Crack Closure Models

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">The proposal of this paper is to review some crack closure models. Christensen discovered the crack closure in 1963, which was later defined by Elber in 1968. The first analytical crack closure model was developed by Newman in 1974, based on the Dugdale crack model.

The Modelling of the Opening and Closure of a Crack

Journal of Vibration and Acoustics, 1995
The paper presents a method which utilizes substructure normal modes to predict the vibration properties of a cantilever beam with a breathing transverse crack. The two segments of the cantilever beam, separated by the crack, are related to one another by time varying connection matrices representing the interaction forces.

Theory for the rate of crack closure

Journal of Applied Physics, 1995
The theory for the constant rate of crack closure was investigated. The aim of this theory is to explain why the rate of crack closure is constant during the wetting stage of healing. Assuming that a surface crack in a material is treated by compression or with solvent, its crack closes up at a constant rate and its shape is independent of time.

The Significance of Fatigue Crack Closure

1971
Experiments on 2024-T3 aluminum alloy sheet are described which confirm the occurrence of fatigue crack closure under cyclic tensile loading. The results show that a fatigue crack can be closed at the crack tip for up to half of the loading amplitude, leaving this portion of the cycle ineffective in propagating the crack.
