A NOTCH INTENSITY FACTOR APPROACH TO THE STRESS ANALYSIS OF WELDS
Fatigue and Fracture of Engineering Materials and Structures, 1998In the context of linear elastic stress gradients that are present in welded joints, a stress field approach based on notch stress intensity factors is presented with the aim of describing stress distributions in the neighbourhood of weld toes, since fatigue strength is dependent on such distributions.

Journal of Applied Mechanics, 1983
In this paper the concept of the stress intensity factor, the underlying mechanics problem leading to its emergence, and its physical relevance, particularly its relation to fracture mechanics are discussed, the reasons as to why it has become nearly an indispensable tool for studying such important phenomena as brittle fracture and fatigue or ...

Evaluation of stress intensity factors
Journal of Strain Analysis, 1975Some of the more useful methods of evaluating stress intensity factors are presented in a concise form. The stress intensity factor is defined and compared with the more familiar stress concentration factor. The shape factor, the parameter which characterizes the shape of the crack, the orientation of the crack and the proximity of other boundaries, is

Stress intensity factors in the presence of contact stresses
Engineering Fracture Mechanics, 1995Abstract In this paper, a loaded tolerance-fit pin in a cracked or uncracked lug is studied. Both symmetrical and non-symmetrical cracks are considered. A symmetrical contact problem due to symmetrical cracks, can be solved automatically. However, non-symmetrical problems can be solved only by re-meshing at each load step if a consistent and smooth ...

Calculation of stress intensity factor from stress concentration factor
Engineering Fracture Mechanics, 1978Abstract Using the general formulas of stress concentration factor, methods for calculating stress intensity factor are mentioned. These methods make use of the several known values of stress concentration and radius of curvature at the point of stress concentration to form expression of stress concentration factor.

DISLOCATION PILE-UPS AND STRESS INTENSITY FACTORS
The Quarterly Journal of Mechanics and Applied Mathematics, 1984The accumulation of line dislocations at a block in a slip-plane is considered. The dislocations are taken to be continuously distributed and their speed is taken to be proportional to the (appropriate component of) stress. The external stress is assumed to be constant.

A Ray Theory for Elastodynamic Stress-Intensity Factors
Journal of Applied Mechanics, 1978Elastodynamic stress-intensity factors generated by the interaction of wave motions with a crack are analyzed. It is shown that in an asymptotic approximation, which is valid for high frequencies, the stress-intensity factors at the edge of a crack are related to the fields of incident rays by a matrix of stress-intensity factor coefficients, which can

Strict Bounds for Computed Stress Intensity Factors
Civil-Comp Proceedings, 2009This paper addresses the subject of local error estimators for finite element methods involving local enrichment. More precisely, we focus on the extended finite element method, which was developed in the last decade for fracture mechanics. We present a method for the calculation of accurate strict bounds of mixed-mode stress intensity factors ...

A Stress Intensity Factor Tracer
Journal of Applied Mechanics, 1985A new optical method, Stress Intensity Factor Tracer (SIFT), has been developed. The device measures continuously the real-time stress intensity factor variation, K1(t), of a moving crack tip using a single, stationary photodetector. The method uses the fact that any variation in K1(t) leads to a change in the intensity of light, I(t), impinging on a ...
