Simulation of superplastic forming with FORGE®
Superplastic forming consists in forming a workpiece within a specific range of process parameters: temperature being close to half of the fusion temperature, very low strain rate, fine and homogeneous microstructure. In this process pressure is applied by a gaz in order to obtain the final geometry.
FORGE® addresses regular superplastic forming as well was superplastic forming combined with diffusion bonding.

FORGE® is used to predict :
- The geometry of the component
- The thickness and detection of possible local necking
- The optimal pressure cycle to maintain superplastic forming
- Easy prediction of flaws
- Easy prediction of thickness throughout the whole process
- Embedded recrystallization laws
- Dedicated remeshing technique for thin products combining highest accuracy level in the thickness and optimal CPU time
