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 ...

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.

On the Stress Intensity Factor of Cracks in Residual Stress Field
Key Engineering Materials, 2007The use of weight function technique in fatigue crack growth subjected to external cyclic loading and residual stress field has been questioned by several researchers in that the technique is unable to account for the residual stress redistribution during the crack growth. In this paper a center cracked tension specimen containing residual stresses was

Stress intensity factors for cracked wedges
International Journal of Solids and Structures, 1981Abstract The elasticity solution to the problem of a cracked semi-infinite wedge is presented. The crack emanates from the wedge apex bisecting the wedge angle. Crack surfaces are subjected to a pair of opposing concentrated forces directed either normal or tangential to the crack plane and located an arbitrary distance from the wedge tip.

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 ...

Rapid Calculation of Stress Intensity Factors
Journal of the Structural Division, 1977A method for computing stress intensity factors for cracks embedded in structural details is described. It consists of adding to accepted solutions for cracks in finite plates and bodies of uniform contour a geometry correction factor which accounts for the stress gradient produced by the geometric discontinuity of the detail. This correction factor is

Intensity of Corner and Stress Concentration Factor
Journal of Engineering Mechanics, 1983The relation between the stress intensity of the corner with an arbitrary angle and the stress concentration factor is investigated. In the thin plate bending problem and the plane elastic problem, the relation is concerned with stress conditions, symmetric to the bisector of a re‐entrant corner angle ranging from 180°–360°.

On the principle of superposition for stress intensity factors
Engineering Fracture Mechanics, 1976Abstract The principle of superposition as applied for stress intensity factors for different types of loading will be discussed. Using an energy formulation, it will be shown that stress intensity factors for different loading types are additive provided all loading types tend to open the crack.

Stress Intensity Factors of Interface Corners
2005 International Symposium on Electronics Materials and Packaging, 2006Stress singularity usually occurs near the interface corners, which may initiate failure of structures. Although several detailed studies have been done about the determination of their associated singular orders and stress intensity factors, very few failure criteria for general interface corners were successfully established based upon these ...

Determination of stress intensity factors
1982The 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
