The effect of the cruciform weld profile and internal defects on the stress intensity factor and the crack growth are investigated using a plane stress, linear, elastic, finite element approach. The stress intensity factors and the propagation and total lives of the cruciform joint with or without internal imperfections are determined for various types of analytical modelling and are compared wth the published results. In addition, stress concentration factors, stress intensity factors, and fatigue lives are also determined for various ratios of plate under tensile and bending loads.
