“…Tests were performed under tensile [ 15 , 21 ], fatigue [ 13 , 22 ], three [ 23 ] and five [ 24 ] point bending to measure shear strength, fracture energy of the joint and bending moment. The delamination behavior of joints was studied using finite element modeling [ 18 , 25 , 26 , 27 , 28 ], and the delaminated surface was examined under a scanning electron microscope [ 29 ].…”

Double strap lap adhesive joints between metal (AA 6061-T6) and composite (carbon/epoxy) laminates were fabricated and characterized based on strength. Hand layup methods were used to fabricate double strap match lap joints and double strap mismatch lap joints. These joints were compared for their strength under static and fatigue loadings. Fracture toughness (GIIC) was measured experimentally using tensile testing and validated with numerical simulations using the cohesive zone model (CZM) in ABAQUS/Standard. Fatigue life under tension–tension fluctuating sinusoidal loading was determined experimentally. Failure loads for both joints were in close relation, whereas the fatigue life of the double strap mismatch lap joint was longer than that of the double strap match lap joint. A cohesive dominating failure pattern was identified in tensile testing. During fatigue testing, it was observed that inhomogeneity (air bubble) in adhesive plays a negative role while the long time duration between two consecutive cycle spans has a positive effect on the life of joints.
