The paper deals with the experimental analysis of the influence of the rivet parameters upon the fatigue strength of aircraft structures. Different riveted samples were tested on fatigue machine taking into account the diameter of the rivet and the forming pressure influence. By superposing the resulting Wöhler curves on the same graphic, some interesting conclusions were pointed.

The paper presents some considerations regarding to the numerical simulation of the behaviour of the riveted structures in fatigue loading conditions. In order to estimate the stress intensity factor, “k”, different constitutive laws for the materials were considered. Choosing different contours for “J” integral calculation, some simplified models were studied. The final numerical results were analysed with respect to the physical tests.
