Behavior of plasticity-induced crack closure and roughness-induced crack closure in aluminum alloy
International Journal of Fatigue, 2001Abstract For center-cracked tension specimens subjected to constant amplitude loading, fatigue crack closure and crack growth behavior in an aluminum alloy 7050-T7451 were investigated. The specimens were tested with stress ratios of −1.0, 0.0, 0.1 and 0.3 under constant amplitude loading.

CLOSURE BEHAVIOUR OF SURFACE CRACKS
Fatigue & Fracture of Engineering Materials & Structures, 1983Abstract— The fatigue crack closure response was investigated for a surface crack in BS4360 50B structural steel, subjected to (1) constant amplitude loading and (2) constant amplitude loading interrupted by a single peak overload. A variety of compliance techniques was employed to determine closure behaviour.

Abstract—A Strip‐Yield Model for Notched Components (SYMNC) model which employs Newman's method of simulating crack closure and determining the effective stress‐intensity factor is used to predict the fatigue crack growth behavior of non‐stress relieved and stress relieved welded joints.

Progressive radial cracking of a clamped plate subjected to crack-face closure is studied. The material behavior is assumed to be elastic-brittle. The cracks are assumed to be relatively long in the sense that the three-dimensional contact problem can be described via a statically equivalent two-dimensional idealization.

The current status of the knowledge about the fatigue crack closure effect is briefly reviewed. A nodel for fatigue crack closure process is proposed, which involves an elastic wedge placed into an elastic crack to simulate the obstruction of crack closure due to asperities or oxide debris.

Analysis of Closure in Fatigue Crack Growth
Journal of Applied Mechanics, 1978A theoretical study is made of the implications of a Dugdale-Barenblatt model for fatigue crack growth under steady cyclic loading. Residual plastic stretches and the effects of crack closure on crack opening and closing loads are calculated by complex function methods for a range of loading ratios.

Effect of crack closure on non-linear crack tip parameters [PDF]
International Journal of Fatigue, 2015 Crack closure concept has been widely used to explain different issues of fatigue crack propagation. However, some authors have questioned the relevance of crack closure and have proposed alternative concepts.

Effect of crack closure on gear crack propagation
International Journal of Fatigue, 2001Computational and experimental studies were performed in order to investigate the propagation of cracking in a spur gear tooth. The stress intensity factors were numerically calculated by the definition of weight functions and by finite element analysis.

Measurability of Crack Closure
1999Crack closure can be measured either with compliance techniques or by means of crack propagation methods. Each of these methods has its own specific limitation. We have performed simulations to show that the results of the measurements with compliance technique near the tip depend strongly on the position of the displacement gages and ...

Abstract A loading stage for the scanning electron microscope has been used in conjunction with the stereoimaging technique to study fatigue crack closure for a center notched specimen of an aluminum alloy. The results are compared to similar measurements from single edge notched specimens of the same alloy and other materials.
