The paper deals with the analysis of the global shell–beam model of a riveted lap joint consisting of six rivets. This is a stage of study of the local physical phenomena in riveted joint [3 – 12]. The contact with friction is defined between collaborating parts of the joint. The calculations are carried out in an elastic-plastic range. The influence of the specimen geometry, boundary conditions, rivet stiffness and the sheet material model on strain and stress fields in the riveted joint is studied. Numerical models are verified on the base of experimental tests. In particular plastic strain fields during tensile loading, stress fields during tensile loading, comparison of numerical results, plastic strain fields around the hole, stress fields in the whole specimen are presented in the paper. Results demonstrated that the specimen geometry has important influence on the stress and strain fields in the final stage of tensile loading. The advantage of the numerical simulation is limiting development costs and improving analysis by giving more complete information about stress and strain fields compared to the pure experimental way. The stress and strain fields can be presented in the neighbourhood of a contact interface, where it is impossible to detect and measure it experimentally.
