The residual stress after self-piercing riveting was predicted using two-dimensional multi-body elastoplastic finite element analysis function. In this representation, the technique of refining the mesh locally near the tip of the rivet as well remeshing was carried out.

Process Validation Forming load accuracy A detailed view of the axisymmetric FE analysis of the riveting process is presented above. The process consisted of two 2024-T3 Al alloy sheets which had to be joined using a 2117-T4 Al alloy countersunk type rivet. The results obtained using AFDEX are compared with experiments as well as a…
