The mechanical strength and failure mode of the adhesive joints was determined by utilizing t-peel and single lap-shear tests and by using macro photo and scanning electron microscope, respectively the effect of three different. Stress analysis on the single-lap spr- adhesive hybrid joint 2018-01-1445 self-pierced rivet (spr) and adhesive are two important joining technologies widely used in automobile industry, and they are often used together to form a hybrid joint. Both joint strength and failure mechanism were found to be highly dependent on adhesive type and overlap length failure load with the two adhesives increased . Users guide to adhesives • determination of dimension of simple lap joint high strength metal-to-metal and metal-to-wood joints, and .

Understanding joint design to optimize adhesive bonding while lap joints allow more bonding area, they can result in offset surfaces being susceptible to peel . Single lap joint test piece was chosen to be tested under impact conditions, as it was reasonably compliant and was already commonly used as a test piece for quasi-static testing of adhesives. The investigational outcome reveals that, as the overlap length of the adhesively bonded single lap joint increases, a substantial increase in the joint strength is observed additionally, it is noted that, with the increase in adhesive thickness, the joint strength decreases. Shear strength of adhesive bonded lap joint the selection of adhesive is dependent on the materials the way from weak temporary adhesives for holding papers in .

High strength adhesives provide potentially efficient load-bearing steel-glass linear distribution approach for determining the stress-state in a lap joint they . Adhesive-bonded double-lap joints d technical report by moderate thicknesses, the limited shear strength of the adhesive may limit the joint strength for thicker . The adhesive properties have a high influence on the joint strength, but a stronger adhesive does not necessarily give a higher joint strength a high strength but brittle adhesive locally achieves high stresses at the overlap corners, but does not allow stress redistributions to the low stressed areas. To reveal the curing temperature mechanism affecting the bonding strength of the phosphate adhesives, several curing temperature curves (ct-1~6) were designed for the single lap joint (slj) using phosphate adhesive.
