Abstract

 

The deep drawing process is one of the most important sheet metal forming processes. The traditional sheet forming techniques used in industry is experimental, expansive and time consuming methods. Prediction of the formability, thickness distribution in deep drawing process will decrease the production cost and time of material to be formed. In this study, a rigid-viscoplastic FEM, using ABAQUES software with anisotropic Hill’s non-quadratic yield criterion is applied to analyze the deep drawing of axisymmetric cylindrical cup. The strains in the radial and circumferential directions have been measured. A correlation on the flange thickness variation by taking into account the work hardening with the experimental values has been searched. The optimal process parameters in the sheets obtained in the simulation were compared with experimental results for various forming conditions. With this regard, the numerical simulations were conducted using the finite element method for cup shaped components with flange. Thickness distribution is obtained for entire cup along with flange. The results obtained from this numerical analysis are compared with experimental findings and results of other researchers. Experimentally thickness distribution is obtained by measurement at various locations in half cut cup along with flange region.
