MIXED‐MODE FATIGUE THRESHOLDS

Fatigue & Fracture of Engineering Materials & Structures, 1982
Abstract— Near threshold fatigue crack growth under mixed‐mode loading and elastic plane‐strain conditions has been studied in 316 stainless steel in laboratory air at room temperature. Particular emphasis was placed on the influence of the mode II component. Crack growth from the starter crack, although initially coplanar, branches to be perpendicular

Mixed mode fatigue crack growth predictions

Engineering Fracture Mechanics, 1980
Abstract This work is aimed at developing a predictive capability for the quantitative assessment of crack growth under fatigue loadings. The crack growth rate relation, Δa ΔN , may involve all three stress intensity factors k1-k3 such that the direction of crack growth may not be known in advance and must be predicted from a preassumed ...

Mixed mode fatigue crack growth criteria

International Journal of Fatigue, 2001
Abstract The behaviour of fatigue crack propagation of rectangular aluminum alloy plates, each consisting of an inclined semi-elliptical crack, subjected to axial loading was investigated both experimentally and theoretically. The inclined angle of the crack with respect to the axis of loading varied between 0° and 90°.

A Model for Mixed-Mode Fatigue

Journal of Testing and Evaluation, 2005
Abstract The initial use of fracture mechanics to characterize crack growth by fatigue was by Paris. Since then, the application of fracture mechanics to fatigue problems has become routine. In the case of fatigue under mode I loading, the method of analysis, under conditions of constant amplitude and small-scale yielding, is well ...

Mixed-mode crack opening in fatigue

Materials Science and Engineering, 1983
Abstract The crack-opening displacements at distances in the range 1–30 μm behind the crack tip were measured in mode I (parallel to the loading axis) and in mode II for the ingot aluminum alloy 7075 in the T651 condition and the similar powder metallurgy aluminum alloy MA-87 using the stereo-imaging technique. A substantial mode II opening was found

FATIGUE CRACK GROWTH UNDER MIXED MODE LOADING

Fatigue & Fracture of Engineering Materials & Structures, 1981
Abstract —Mixed mode fatigue crack growth is analysed using Sih's strain energy density approach. A centre crack panel geometry loaded under uniaxial cyclic tension is considered. The crack angle is varied from 30° to 90°. A procedure for the determination of crack propagation life is outlined.

Fatigue Crack Growth in Mixed Mode Loading

Journal of Engineering Materials and Technology, 1991
In this paper, a direct approach based on the mixed mode Dugdale model, the accumulated plastic displacement criterion for crack propagation and the cyclic J-integral concept is used to develop equations to predict the mixed mode fatigue crack growth.

A mixed mode fatigue crack closure model

Engineering Fracture Mechanics, 1985
Abstract Fatigue crack closure conditions leading to mixed mode crack-tip stress states are discussed. A closure model based on contact between impinging fracture surface asperities is introduced. Asperity angle, magnitude of mode II interference, friction between contacting surfaces and distance of the contact surfaces from the crack-tip are ...
