Abstract:

The main aim of this paper is to find the more dominant parameter of deep drawing, out of two parameters namely DR (Die Radius) and BHF (Blank Holding Force). In order to accommodate these two parameters simultaneously, FE models of sheet metals are generated by varying the Die Radius (DR) and BHF (Blank Holding Force). These generated FE models are analyzed using FE Explicit Dynamics analysis LS DYNA by varying DR and BHF in FE models to determine the Vonmises stress of the sheet metals. Non-linear response surface regression analysis was carried out to fit response surface for vonmises stress obtained from FE numerical analysis results taking the DR and BHF as input variables. From the regression analysis, it is found that Die Radius is more dominant factor than Blank Holding Force.

Key Words:

Sheet metals –Deep Drawing- Vonmises Stress, Die Radius (DR), BHF (Blank Holding Force) – FE Explicit Dynamics analysis LS DYNA
