Mechanics of mixed mode small fatigue crack growth

Engineering Fracture Mechanics, 1987
Abstract An elastic-plastic analysis of a mixed mode crack was conducted under general yielding conditions using a finite element method. Based on the finite element analysis, a formula of the J-integral was developed, and the behavior of the crack opening or sliding displacement was investigated. Crack growth mechanics was discussed to explain mixed

Using a Mixed-Mode Fatigue Delamination Criterion

1996
This paper applies a mixed-mode delamination onset criterion to predict edge delamination in quasi-isotropic laminates of IM7/8320 and IM7/5260. The laminates were tested statically and in fatigue at 23 and 175°C. The three stages involved in this process were: (1) determination of the mixed-mode ratio, (2) determination of the mixed-mode delamination ...

Mixed mode fatigue crack growth: A literature survey

Engineering Fracture Mechanics, 1996
The applications of fracture mechanics have traditionally concentrated on crack growth problems under an opening or mode I mechanism. However, many service failures occur from growth of cracks subjected to mixed mode loadings. This paper reviews the various criteria and parameters proposed in the literature for predictions of mixed mode crack growth ...

Simulation of mixed mode fatigue crack growth

Computers & Structures, 1991
Abstract The computation process including ADINA for predicting crackpath and structure lifetime under mixed mode loading is presented. Using the results of a FEM analysis, the J -integral is computed. The separation into J 1 , and J 11 leads, in the case of linear elastic material behaviour, to the stress intensity factors K 1 and K 11 ...

Plane stress mixed mode fatigue crack propagation

Engineering Fracture Mechanics, 1995
Abstract A complex crack trajectory has been obtained by subsequently changing the orientation of a straight crack at the center of a thin circular disk of aluminum 2024-0 with respect to uniaxially applied constant amplitude fatigue loading. The propagation of the main crack has been performed by producing a series of kinks and pseudo-asymmetric ...

Mixed-mode fatigue crack growth under biaxial loading

International Journal of Fatigue, 1984
Abstract Studies on crack growth in a panel with an inclined crack subjected to biaxial tensile fatigue loading are presented. The strain energy density factor approach is used to characterize the fatigue crack growth. The crack growth trajectory as a function of the initial crack angle and the biaxiality ratio is also predicted.

Experimental observations on mixed mode fatigue crack propagation

International Journal of Pressure Vessels and Piping, 1993
Abstract Fatigue crack propagation experiments were conducted on D16AT Al alloy to study the effect of load ratio on mixed mode fatigue crack propagation. The experiments were conducted on a Compact Tension Shear specimen at different crack angles in both mode I and mixed mode conditions.

Mixed Mode Fatigue Crack Growth Related to Widespread Fatigue Damage

1995
The problems associated with fatigue were brought to the forefront of research by the structural failure of a transport category aircraft in 1988. This failure was attributed to the occurrence of multiple cracking which has since been termed “Widespread Fatigue Damage” (WFD).

A Mixed Mode Fatigue Crack Growth Model Applied to Rolling Contact Fatigue

World Tribology Congress III, Volume 2, 2005
Extended finite element method simulation were conducted in order to evaluate mode I and II stress intensity factors (SIFs) for cracks under cyclic contact rolling and rolling-sliding conditions. The crack propagation mode and direction were investigated using criteria.
