Fatigue Crack Closure Analysis and Crack Propagation Estimation

1984
The purpose of this paper is to model analytically fatigue crack growth with a plasticity-induced crack closure effect in constant amplitude loading. The specimen considered in modelling is a centre-crack tension (CCT) one of 2219-T851 aluminium alloy.

Three dimensional crack closure measurements

23rd Aerospace Sciences Meeting, 1985
This paper describes fatigue crack growth and retardation experiments conducted in polycarbonate test specimens. This transparent model material allowed optical interferometry measurements of through-the-thickness fatigue crack opening profiles. Crack surface displacements were then obtained through the specimen thickness and are discussed in terms of ...

Long Fatigue Cracks — Microstructural Effects and Crack Closure

MRS Bulletin, 1989
Fracture mechanics technology is an effective tool for characterizing the rates of fatigue crack propagation. Generally, fatigue crack growth rate (da/dN) in each loading cycle can be presented as a function of stress intensity range (ΔK), where ΔK=Kmax—Kmin,KmaxandKminare the maximum and the minimum stress intensities, respectively.

Fatigue crack closure after overload

Engineering Fracture Mechanics, 1983
Abstract The fatigue crack closure after overload was measured by small foil strain gages. The effect of overload on crack closure stress and crack propagation rate was observed to extend over a range several times larger than the overload plastic zone.

Crack Closure: Correlation and Confusion

1988
Some aspects of crack closure are reviewed and examined with respect to one's ability to predict fatigue crack propagation rates in engineering alloys. The development of artificial crack closure with the placement of shim stock in the crack mouth provided nonconservative estimates of crack growth rates as compared with those rates for specimens ...

Pinball Tendons Crack Closure Technology

Proceedings of the Cardiff University Engineering Research Conference 2023
Concrete is a popular construction material due to its unyielding nature. Although concrete is resistant to erosion, rotting, and rusting, due to its low tensile strength, reinforced concrete is prone to cracking. Also, because the cracks expand and become bigger over time, they can be a potential risk for concrete elements and lead to the failure of ...

Mechanics of Fatigue Crack Closure

1988
Description Covers fatigue crack closure from materials characterization to practical application in industry. Peer reviewed papers provide information and experiences on new crack-closure measurement techniques, advanced crack-closure analysis methods, and practical applications of the crack-closure concept to predict crack-propagation ...
