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.

Fatigue thresholds under mixed-mode (I+III) loading

International Journal of Fatigue, 1991
Abstract A model is presented to describe the propagation of mode-l fatigue cracks under mixed-mode (I+III) fatigue conditions in angled-crack three-point-bend specimens. The onset of mode-I crack growth is governed by the orientation and the crack opening displacement of the fatigue cracks.

Fatigue crack growth studies under mixed-mode loading

International Journal of Fatigue, 2001
In this study, the growth behavior of fatigue cracks in AISI-304 stainless steel samples under mixed-mode (mode-I and mode-II) loading conditions was studied by utilizing Compact Tension Shear Specimen (CTS) geometry. The results indicate that, at low load mixities, both the strain energy density criterion and the maximum stress criterion estimate ...

Mixed-Mode Creep and Creep/Fatigue Crack Growth

1991
Pure mode-I, pure mode-II and mixed-mode fatigue, creep and creep/fatigue crack growth tests have been carried out on Jethete M152, an aeroengine casing material, at 550°C. A reasonably good correlation of the creep crack growth rates was obtained using the C* parameter.

Mixed-Mode Fatigue Crack Growth in Orthotropic Steel Decks

Key Engineering Materials, 2006
The strain energy density factor approach under mixed-mode condition is used for the prediction of crack propagation in the orthotropic steel deck specimen, which is similar to that of existing suspension bridges. Stress intensity factor approach is used to compare with strain energy density factor approach for the fatigue crack growth analysis.

Fatigue crack propagation trajectories under mixed-mode cyclic loading

Engineering Structures, 2003
Abstract As the direction of the mixed-mode fatigue crack growth may not be known in advance, a new methodology is proposed to simulate the fatigue crack trajectories under general in–plane cyclic loading. The accumulated elastic strain energy is calculated in the vicinity of the crack tip for all possible prospective propagation directions.

Short fatigue crack growth behavior under mixed-mode loading

International Journal of Fracture, 2010
Mixed-mode loading represents the true loading condition in many practical situations. In addition, most of the fatigue life of many components is often spent in the short crack growth stage. The study of short crack growth behavior under mixed-mode loading has, therefore, much practical significance.

Mixed-Mode Fatigue Failure in Structural Adhesives

1999
Fatigue data obtained under biaxial loading conditions for adhesively bonded joints are used to plot S-N type diagrams to assess the effects of biaxiality in loading. Independently Loaded Mixed-Mode Specimens (ILMMS) are used for data collection purposes.
