Load capacity of single-lap adhesive joints made of 2024-T3 aluminium alloy sheets after shot peening

Abstract The goal of the work reported was to determine influence selected shot peening parameters on deflection Almen strip and load capacity single-lap adhesive joints made 2-mm-thick aluminium alloy EN AW-2024-T3. Moreover, research aimed at checking possibility using indicator predict after peening. analysis carried out according Hartley’s PS/DS-P:Ha3 plan. input factors were parameters: treatment time t (60–180 s), ball diameter d k (0.5–1.5 mm) compressed air pressure p (0.3–0.5 MPa). It has been proved in this that outer surface can be used strengthen joint. maximum increase peened 33.4%. observed decreases with an (in assumed area variability technological parameters). results obtained indicate adoption too intensive treatment, manifested high values strip, may weaken joints.
