Abstract

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.
