Many engineering specifications, manufacturing procedures, inspection and quality controls require the evaluation of the residual stress of critical parts of components. The finite elements analysis (FEA) provides a simulational advantage and it is very helpfully in projects aiming manufacturing improvements, thus reducing costs in terms of time and money. This study had as proposal to improve the database of the analysis systems using FEA extending the knowledge of the residual stresses phenomena in wheels using extensometers. To this work were use strain gage to acquire and make available this information available. The residual stress values obtained from the experimental tests by drilling method with rosette type strain gages. The region to test is a critical region (the spokes), showed on FEA simulations. The relevance of the present study and research on residual stresses meets the required effort towards the safety improvements in car’s wheel industry.
