Aluminum Flow Simulation to Severe Plastic Deformation by Multiaxial Forging

Abstract:

By plastic deformation processing techniques is possible to achieve parts with complex geometric configuration and superior mechanical characteristics required in many industries such as aerospace, energy, transport etc. These parts are subjected to high loads or involves a special safety in operation and therefore can not be achieved by empirical design techniques. In addition, industrial development requires obtaining parts with smaller dimensional deviations without defects from expensive materials which are manufacturing in smaller series. To cope with these trends in the currently processed by severe plastic deformation is necessary to apply plastic deformation simulation using finite element method. Aluminum flow simulation is necessary for plastic deformation predetermination the total force, which is used to choose the machine deformation. Also through flow simulation aims to determine contact stress material - deformation tools, necessary stress dimensioning tool, in this case the active plate, punch and counterpunch.
