Abstract
One of the most sensitive features of sheet metal forming processes is the elastic recovery during unloading, called spring back, which leads to some geometric changes in the product. In this paper spring back dependence on the mechanical properties of different materials and tools geometry has been examined numerically and experimentally in sheet metal U- bending test. The computer code MARC was used to simulate the U- bending process under plane strain condition. A Comparison between the experimental and the finite element simulation results also performed. A complete knowledge of the spring back phenomenon and its dependence on material and process variables is strongly required in order to develop effective real time process control systems.
