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.

On the geometry of fatigue crack closure
Steel Research, 1992Long fatigue cracks frequently grow at a much lower rate than short cracks because they are closed during part of the stress cycle. The critical crack length for the transition from “short” to “long” depends on the amplitude of stress intensity ΔK and on the stress ratio R. This dependence is explained using a numerical study of the crack flank contour.

Theory for the rate of crack closure
Journal of Applied Physics, 1995The 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
1971Experiments 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.
