| Abstract: | The total Lagrangian finite element formulations for three-dimensional elastic-plastic sheet metal finite deformation are deduced according to the nonlinear continuum mechanics theory,and their matrix formulations are given on the first time. The deformation process of semisperical punch stretching of circular sheets has been simulated. The results obtained from application of the simulation procedure developed in this paper agree with the existing experimental data. |
