Constant amplitude loading fatigue tests were carried out for 7075/2A12 dissimilar aluminum alloy friction stir welding (FSW) lap joints, and the fatigue fracture characteristics were observed accordingly. Experimental observation suggested that the effective lap sheet thickness had a salient effect...
