Title

Rückfederung beim Tief- und Streckziehen von Feinblechen

Other Title
Spring back in deep and stretch drawing of light sheets
Abstract
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.
