Abstract (EN): With advances in sheet metal forming sectors there are instances (Embury and Duncan 1981)(Silva et al. 2008) where the use of conventional forming limit curve (FLC) is not accurate. For this reason recently researchers (Atkins 1996; Isik et al. 2014) have started using modified forming limit diagram (FLD) which rely on fracture limits rather than necking limit as in the case of FLC. This study involves numerically simulating and replicating these fracture limits for Copper as material. Load-displacement graph is used to validate the accuracy of the simulation when compared to experimental values. The study so far shows good prediction of fracture and possibility to plot the FLD with fracture limits using these simulations. These simulations give very good insight to the stain path followed by the specimen before its fracture.
