“…Adhesive joints are commonly used in different industries and in many cases they are a good alternative to traditional mechanical connections. The advantages of adhesive joints include, among others, the possibility of reducing the weight of the structure, good sealing and damping properties, no need to make holes and the ability to combine various materials and elements of different thickness [4,21]. The most popular type of adhesive joints is lap joint [18].…”

The aim of the article was to determine the influence of shot peening of the outer surface of the overlap on the stress state in the adhesive layer and the load capacity of single lap adhesive joints made of EN AW-2024-T3 aluminum alloy. Experimental investigations and numerical simulations were carried out. According to the results of experimental analyses, shot peening with balls with a diameter of 1 mm for 120 s with a compressed air pressure of 0.5 MPa increased the load capacity of the adhesive joints by 33%. Numerical simulations have shown that shot peening, by deforming the joined elements, reduces the stress perpendicular to the surface of the adhesive layer which results in a reduction of equivalent (von Misses) stress and an increase in strength of adhesive joints.
