This study had as proposal to improve the knowledge of the residual stresses phenomena in wheels and expand the database of the computer systems from finite elements analysis (FEA). X-ray diffraction (XRD) was used to acquire and make this information available. Now engineering specifications, manufacturing procedures, inspection and quality controls require the evaluation of the residual stress of critical parts of components. This is becoming a commonplace such as the demands for mechanical properties data. The residual stress in metal and alloy components arises as a result of manufacturing processes by which was attained the shape of the desired component. The work was undertaken aiming, specifically, the evaluation of light-alloy wheels cast of AlSi7 alloy for use in passengers cars. The residual stress values from XRD and hole drilling method of the experimental tests on the spokes were compared with simulation data. Sometimes simulation system needs correction of data of the effect of plasticity. Those presented values of residual stress demonstrated the existence of convergence to the values of experimental tests and values calculated using FEA simulation software. The relevance of the present study and research on residual stresses meets the required effort towards the safety improvements in car’s wheel industry.
