Abstract
It is shown that smoothing of the metal surface on the boundaries of sheet tee joints of aluminium and elimination of angular deformation by high-frequency peening provide a lowering of the values of stress concentration factor 1.6 times. Joint peening increases the ultimate fatigue strength by 40 % at zero-to-compression and by 10 % at repeated stress cycles.
Keywords: aluminium alloys, welded tee joints, joint profile, angular residual deformation, stress concentration, high-frequency peening, fatigue resistance
