The FEM analysis of effect of self-piercing riveting process parameters on joint quality is one of modern and economically effective ways of optimal model realization [10] and [11]. By using the numerical analysis the size and distribution of the residual stress in the joints can be determined [12] and [13]. Witek [12] conducted an stress variation analysis for the joints with tubular rivet. Mucha [13] drew attention on the tools shape influence on the rivet blocking and also on the stress level in the SPR joint. One of recent papers presenting the numerical analysis of self-piercing riveting (SPR) with tubular rivet is paper published by Han et al. [11]. They carried out a numerical simulation of the tools shape optimization for the best rivet blocking. However, they Reparixin did not take into account the stress level in the joint. The size of the residual stress influences on the static strength and fatigue of the riveted joint. The full FEM 3d model of the joint loaded statically and dynamically was presented by Mohammadpour et al. [14]. The changes in the material structure are caused by the plastic deformation and by the galvanic corrosion. The corrosion influence on the SPR joint damaging mechanism was presented by Calabrese et al. [15]. The type of used rivet has an effect on SPR joint lock formation and also influences the fatigue strength and joint destruction method [16]. Some of the recent papers with the size of stresses and strains in the SPR joint determination are the work of Haque et al. [17] and [18]. They used the neutron diffraction technique. Method of the measurement error reducing, for a small area observation in the SPR joint, was presented.
