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.

Extension of Mixed‐Mode Fatigue Cracks in Steel Samples

Journal of Applied Mechanics and Technical Physics, 2004
Experimental studies of the extension of mixed‐mode fatigue cracks were performed on rail steel samples. The direction of growth of fatigue cracks was studied for three types of loading: alternate transverse shear and transverse and longitudinal shears under compressing stresses.

Effects of Mixed Mode and Mode II Overloads on Mode I Fatigue Crack Growth

1987
Damage caused by fatigue crack growth occurs in several machines and plant components. In order to give an accurate prediction of fatigue lives or inspection intervalls the influence of variable amplitude loading respectively of single peek overloads under mixed mode and mode II must be understood.
