“…First, the hook defect tends to result in larger extent of sheet thinning in contrast to the cold lap defect; second, the sharp-curved character of the hook defect introduces a significant stress concentration at the tip of the hook. These two factors promote easier crack propagation along the hook defect as the applied load is increased, and the phenomenon of lower fracture load in AS loading compared to RS loading has been reported by many researchers (Ref 4,(10)(11)(12).…”

“…1. Failures of friction stir lap joints are commonly found to occur along these defects (Ref 6,(9)(10)(11). In comparison to the cold lap defect on the RS, the hook defect on the AS exerts more negative effects on the mechanical properties of friction stir lap joints.…”

“…The author argued that this was because the hook defects on AS did not negatively affect the transmitting load capability of the welded joints, but a deeper explanation was lacking. On the other hand, the phenomenon of higher fracture strength in RS loading compared with AS loading has been reported by other researchers [12,13]. The smaller extent of sheet thinning and lower stress concentration on the RS were considered to be the main reasons for the higher fracture strength of RS loading.…”

“…The sheet thinning level caused by the hook and cold lap defects has been demonstrated to play a prominent role in determining the performance of lap joints [6][7][8][9][10][11][12][13]. Yuan et al [13] reported that the crystallographic texture was another factor that influenced the fracture load and fracture path of FSLW joints of AZ31 magnesium alloy.…”
