Stress intensity factor for a tee-shaped weldment

Abstract An expression for the stress intensity factor in a tee-shaped weldment loaded in bending is developed by modifying 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.
