An Integrated Approach to Sheet Metal Forming Simulation

This paper presents the application of the different approaches available for the analysis of the sheet metal forming process on an industrial part (RENAULT KANGOO front fender). It is nowadays accepted in the engineering community that inverse, simplified direct and incremental direct approach are complementary and should be used in the development of a stamped part. The paper shows the formability analysis of the TWINGO door and hatchback at different stages of the part and process design, identifies the optimal approach at different stages and gives indication as to the relative speed, accuracy and quality of the different simulation solutions.
