NUMERICAL SIMULATIONS OF SHEET-METAL FORMING

The objective of this paper is to discuss the numerical solution of sh eet-metal forming applications using the ABAQUS general purpose implic it and explicit finite-element modules. The three conference benchmark problems of NUMIFORM'93 are used as examples in the paper. The analys es were performed using combinations of the implicit and explicit vers ions of ABAQUS. The numerical-modeling techniques used in these analys es are discussed. The effectiveness and suitability of the implicit an d explicit finite-element procedures for each of the benchmark problem s are discussed.
