Simulation of sheet metal forming with FORGE®

Sheet metal forming is used for manufacturing thin products. The process can be carried out as a cold or a hot forming process (Hot Press Forming, HPF). 

FORGE® simulates both types of sheet metal forming operations in order to optimize process parameters and to ensure the parts’ quality.

The example presented here corresponds to the hot forming of a middle riser of automobile bodywork. Following the stamping operation, the part formed is cooled between the two dies which makes it possible to check its microstructure and its final shape. The FORGE® software can be used in this type of configuration and considering the microstructural changes.


predictive simulation

FORGE® allows accurate prediction of:

  • Final shape with the prediction of final thickness,
  • Defects like striction,
  • Residual stresses,
  • Press loads including loads to apply on the blank holders,
  • Metallurgic changes in the case of Hot Press Forming.
