Analysis of Flange Behaviour of Non-Axisymmetric Deep Drawing in Intial Stage by Finite Element Method

The flange deformation of non-axisymmetric deep drawing in the initial stage is analyzed using finite element method. The direction of principle stress, metal flow behaviour, the spread of plastic zone, and the stress or strain distribution are thus obtained. A comparison has been made between the results by finite element method and that of experiments for aluminum sheet (including moire), showing good agreement.
