This note concerns the Mode I stress intensity factors at edge cracks in strips under pure bending. When these cracks penetrate three quarters or more of the width of the strip, expressions in standard handbooks can give rise to distinctly different results for K~. By applying an appropriately teste
Accurate finite element analyses of compact tension specimens have been performed giving stress intensity factors slightly above those of existing analytical solutions. Crack mouth openings are also grven. Simple formulae for both stress intensity and crack opening yielding errors within a couple of
The problem of a beam containing a semi-elliptical surface crack and subjected to tension or bending loading is investigated. The stress-intensity factor along the crack front can be calculated assuming a model with finite strips arranged in series and parallel. Several cases are analysed varying th
Abstrac&--This paper develops expressions for the stress intensity factor and energy release rate at the existing notch tip of a three-point bend specimen. These expressions are based on the true state of stress at the notch tip and are therefore likely to give an improved estimate of the fracture t
