Superplastic forming

Superplasticity is a state in which a material is deformed well beyond its usual breaking point (high T, ultra low strain rates).

Multisheet superplastic forming of a self-stiffened titanium structure (Sonaca).

When pressed together, sheets got welded dur to diffusion bonding.

Optimal pressure cycle is computed in order to stay below a given plastic strain rate.

Importation of an industrial geometry including NURBS curves and surfaces.

Superplastic Forming with optimization of the applied pressure cycle.
