Abstract

The majority of the repair processes of the car bodies introduce residual tensions in the material, because the use of special work technologies, and heterogeneities as consequence of the application of putties, with different mechanical properties in comparison to the original sheet. The election of the repair process depends of the damage severity and it has important effects on the repair costs and the reliability of the vehicle. The variation of the elastic limit in elements of car body that have suffered an impact and later they have been repaired by different procedures is analyzed in this work. The results obtained for steel elements and two conventional processes of repair have been presented. The aim is to determine the repair process that produces a minor affect on the initial properties of the material. Finite elements simulation has been used to complete the tests.
