Stress intensity factor solutions for fretting fatigue using stress gradient factor

Engineering Fracture Mechanics, 2017
Abstract This paper presents stress intensity factor (SIF) solutions for fretting fatigue conditions by including a stress gradient factor (SGF) to correct the classic geometry factor for tension semi-infinite strip (TSIS) specimen. This gradient factor considers the stress gradient due to the pressure of the pad on the surface of the specimen, which

Dynamic Stress Intensity Factor

2003
An infinite strip of height 2h with a semi-infinite crack is rigidly clamped along its upper and lower faces at y = ± h (Figure 1). The upper and lower faces are moved in the positive and negative y-direction over distances u0, respectively. Determine the dynamic stress intensity factor K(t) during steady state crack propagation.

Stress intensity factors for interacting cracks

Engineering Fracture Mechanics, 1987
Abstract Experimental stress intensity factors (SIFs) for two interacting straight cracks in plane-homogeneous regions were determined. Photoelastic data were collected from digitally sharpened isochromatic fringe patterns by using a digital image analysis system. SIFs were extracted by using the field equations derived from Williams' stress function.

Stress intensity factors in fretting fatigue

The Journal of Strain Analysis for Engineering Design, 1979
Solutions are derived for mode I and mode II stress intensity factors for a crack at the edge of a sheet subjected to localized fretting forces. Both normal and tangential forces are considered. These solutions are approximated by a polynomial function of crack length, which is then used as a Green's function to derive stress intensity factors for ...

Extended Stress Intensity Factor Concepts

2013
The stress intensity factor concept for describing the stress field at pointed crack or slit tips is well known from fracture mechanics. It is substantially extended here in two directions. One extension refers to pointed V-notches with stress intensities depending on the notch opening angle. The loading mode related notch stress intensity factors K 1,

Summary of Stress-Intensity Factors

1996
Abstract The stress-intensity concept is based on the parameter that quantifies the stresses at a crack tip. This article summarizes some stress-intensity factors for various crack geometries commonly found in structural components. Through-the-thickness cracks may be located in the middle of a plate; at the edge of a plate; or at the ...

Determination of stress intensity factors

1982
The application of fracture mechanics principles bears largely upon the stress intensity factor. An essential part of the solution of a fracture problem in linear elastic fracture mechanics is the establishment of the stress intensity factor for the crack problem under consideration. Since the introduction of fracture mechanics much effort has been put

Thermo-mechanical stress intensity factors evaluation

Nuclear Engineering and Design, 2010
This paper deals with the evaluation of the static mixed-mode stress intensity factors in case of thermal and mechanical loadings. A method and a formulation based on the J-integral and the energy release rate formulation is developed. The numerical results emphasize the effects of the temperature field on the stress intensity factors; thus, we show ...
