Abstract
Wrinkling of conical cups was simulated using the finite element method (FEM) and verified experimentally. Two different FEM codes: static-explicit ITAS3D and dynamic-explicit ABAQUS/Explicit were used in numerical simulations. It was found that several parameters could affect results of wrinkling simulation. Most important was the initial shape of the finite element mesh. General difficulties in simulation were reported for both FEM codes, dynamic and static. Stamping of conical cups was conducted using an anisotropic steel sheet to establish a reference frame for the validation of numerical results.
