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
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 purpose of the present investigation was to design a simple specimen for which the stress intensity factor (K) is constant for a substantial range of the crack length. Moreover the crack growth direction should be stable without the necessity of side grooves. The geometry adopted was a rectangul
