Deep drawing, as the main technology for obtaining car body parts, is one of the fields where the virtual design of parts and process is used for product development. The use of FEM in sheet metal forming processes is an efficient tool of virtual design that has replaced the physical try-out method in terms of costs and time consuming. In the paper steps necessary in virtual design and verification of a car body part are presented. The design process starts with the design analysis and the creation of the part model using reverse engineering. Then the model is analyzed using FEM. By numerical simulation is obtained the form and the dimensions of the blank. After defining the deep drawing tool the process of deformation is modeled. An analysis of part, in terms of geometry, thickness and stresses variation is made. It is presented the module of forming limit diagram of the program and the results of the analysis of the part using this module. Finally, the results of this study could be used and improved by the car manufacturers.
