In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically.  Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process.  The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process.  Also, the...

The numerical simulation of problems involving contact with friction between deformable and rigid bodies is highly dependent of the predicted contact conditions, which are continuously changing during the process. In the case of sheet metal forming processes, the forming tools are assumed to behave rigidly, and thus only the definition of the outer surfaces is required for the simulation. This ...
