摘要
In this paper, analytical stress intensity factor solutions for welds in lap-shear specimens of different materials and thicknesses under plane strain conditions are presented in the normalized forms. The stress intensity factor solutions for welds are expressed in terms of the structural stresses based on a strip model. The analytical stress intensity factor solutions are selectively verified by the results of the two-dimensional finite element analyses. The interface crack parameters for the stress intensity factor solutions for welds in lap-shear specimens of dissimilar steel, aluminum, magnesium, and copper sheets are listed for different thickness ratios. The analytical stress intensity factor solutions are obtained and selectively presented in the normalized forms as functions of the specimen thickness ratio for the combination of aluminum and steel sheets for fracture and fatigue analyses.
