Forming Limit Curves are valid for one particular material alloy, temper and gauge combination. However material properties vary from batch to batch due to variation in the production process. For there a single Forming Limit Curve can not be an exact description of the forming limit. Several resear

## Abstract A numerical simulation of an active media based forming process has been carried out by means of the finite element method, where molten plastic was used as pressure medium. The material behaviour of the sheet metal component has been modelled in the FEA package Ls‐Dyna with a temperatu
