ON FINITE ELEMENT SIMULATION OF SHEET METAL FORMING PROCESSES IN INDUSTRY

During the last few years an enormous progress in the industrial use of numerical tools for the simulation of sheet forming processes has taken place. This is especially true for the automotive industry. The present paper tries to give a brief introduction to the subject of practical sheet metal forming, and to describe some of those forming defects, which can occur. Thereafter, a state-of-the-art review of methods and procedures for sheet forming simulation in practical use today will be presented. This concerns especially various Finite Element formulations used for the current application, including a brief historical review on the subject. Finally, some shortcomings of today's simulation technology will be described.
