EN The paper deals with the analysis of deformation of a rivet hole in a riveted joint after the manual dynamic riveting process. For many years, riveting remains a traditional and the most popular method of joining in aircraft structures. The residual stress and strain state appear at the rivet hole after the riveting process, which improves the joint's fatigue behaviour. The local finite element models are made with Patron. The rivet and sheets are described using eight-noded, three-dimensional brick elements. The riveting tools consist of four-noded, two-dimensional shell elements. Numerical FE simulations of the upsetting process are carried out using the Ls-Dyna code. The contact with friction is defined between the collaborating parts of the specimen. The results of simulations of the dynamic riveting process of a mushroom rivet with and without a compensator are compared in this paper. Hole deformation of the upper and lower sheet, squeezing force, as well as deformations of the rivet head are analysed. The influence of the compensator on strain and displacement states is studied. Simulation shows that some technological factors may have positive influence on the residual stress fields. Using the rivet with a compensator results in a better rivet hole filling capability. The rivet hole displacement in upper and lower sheets are at the same level. Paper also present manual dynamic riveting process ofreverse and standard riveting procedure and model of riveted specimen.
