โฆ Synopsis
An expression for the stress intensity factor in a tee-shaped weldment loaded in bending is developed by m~ifying a solution for the three-point bend specimen and by modifying a solution developed by Newman and Raju. The developed expression is rearranged and integrated over empirically determined bounds to estimate the fatigue life of the weldments. Estimated fatigue lives compare favorably to experimental data.

## A~~ct-Applying Smith's solution for a semi-circular flaw, an approximate expression is derived for a corner flaw emanating from an edge of a quarter infinite solid. The maximum stress intensity factor on the periphery of the flaw is found to be K = ~420. The same expression can be obtained if a
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
