We propose an experimental procedure aimed at estimating crushing stresses in multirow riveted joints of duralumin plates based on noncontact optical methods. According to the results of experimental investigations of specimens with one rivet, we plotted fracture diagrams of local volumes of the material on the stress–strain coordinates and determined the admissible crushing stress corresponding to a residual elongation of the hole by 2%. According to the determined level of strains in the local volume of a?single riveted joint, we computed the level of crushing stress near separate rivets of the multirow joints. The proposed procedure can be used to establish the distribution of crushing stresses and the degree of damage to the riveted joints in the fuselage skin of the aircraft.
