Stress Intensity Factor of a Corner Crack

1976
The alternating method for elliptical crack analysis, which is based on the combined use of a pressurized crack solution and a free surface solution, has been limited in its application due to convergence difficulties in the iteration process. By prescribing appropriate fictitious pressure on the elliptical crack surface, which protrudes into the free ...

Stress intensity factors for threaded connections

Engineering Fracture Mechanics, 1995
Abstract A generic stress intensity factor (SIF) solution for threaded connections is presented in this paper. This is based on multiple reference state weight function theory, making it applicable to any mode I crack emanating from a thread root.

Stress Intensity Factors for a Linear Stress Distribution

2003
The stress intensity factor for an edge crack of length a in a semi-infinite plate subjected to a pair of equal and opposite concentrated forces at a distance b from the plate edge (Figure 1) is given by [1] $$ K'_I = \frac{2} {{\sqrt \pi }}\frac{{1 + F\left( {{b \mathord{\left/ {\vphantom {b a}} \right.

Stress intensity factors in spot welds

Engineering Fracture Mechanics, 2002
Abstract This paper looks at stress intensity factors of cracks in resistance spot welded joints. Stress intensity factors have been used in the past to predict fatigue crack propagation life of resistance spot welds. However, the stress intensity factors from all previous work was based on assumed initial notch cracks at the nugget, parallel to the ...

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,

Bounding theorems for stress intensity factors

Engineering Fracture Mechanics, 1983
Abstract Bounding theorems for the changes in elastic energy due to a crack in a finite body and crack tip Stress Intensity Factors are established by use of the variational principles of the theory of elasticity. It is shown that the change in elastic energy due to a crack in a finite body is larger than the change in energy due to the same crack in

Stress Intensity Factors for Notched Configurations

Journal of Testing and Evaluation, 1985
AbstractA method is presented for approximating stress intensity factors for notched-configurations without cracks. It is expected that estimates obtained from such analyses, which are outlined in the text and detailed in the Appendix, should be useful in estimating the failure load in a notched structure behaving in an idealized elastic manner ...

Calculation of Stress Intensity Factors by Integration

2003
Use Problem 5 to determine the stress intensity factor for a crack of length 2a in an infinite plate subjected to uniform normal stress σ and shear stress τ along the upper crack surface from x = b to x = c. Then determine the stress intensity factor when the same stresses apply to the lower crack surface.

Rapid Calculation of Stress Intensity Factors

2008
The demand to design evermore efficient, economic and safer structures continues and is set to only increase throughout the twenty-first century and beyond. Thus, the challenges confronting the engineer, concerned with ensuring a state of structural integrity prevails similarly grow evermore demanding.
