PAM-STAMP Superplastic Simulation

Superplastic forming with PAM-STAMP

Superplastic forming is a peculiarity in the mechanical behaviour of certain aluminium and titanium alloys, whereby extremely high levels of ductility can be obtained, allowing the successful forming of challenging shapes which would be otherwise impossible. Used in the Aerospace industry for many years, it is increasingly used in Automotive industry for low volume vehicles.

However, designing this process to make sure the full potential of these expensive materials is used, is complex and difficult. PAM-STAMP has built-in modules to help find the optimal process layout and process parameters to optimize process time and material usage.

Superform USA relies on PAM-STAMP to iteratively design complex tools and prove feasibility virtually.
