Abstract
The philosophy, limitations and methods of fatigue crack propagation life calculations are discussed. Calculations are presented for the effects of bending stresses, undercut, weldment thickness, and internal defects upon the fatigue crack propagation life for butt welds. The methods have also been applied to a fillet weld geometry.
