The material properties of 5 sheet metal materials are described by plasticity parameters. The geometrical deviations caused by spring back have been determined by experimental investigations in deep and stretch drawing. Influences of materials properties and forming conditions on type and amount of spring back have been appointed. These results have been compared with FEM-simulation.
