Inverse form finding aims to determine the optimum blank design of a workpiece whereby the desired spatial configuration that shall be obtained after a forming process, the boundary conditions and the applied loads are known. As a verification of the optimal material configuration a subsequent direct FEM computation has to result in the desired shape of the deformed workpiece. In this contribution the inverse FEM, which formulates the mechanical weak form in the spatial configuration and solves it with respect tothe material configuration, is used to obtain an admissible blank configuration. An example of applying this inverse method to a contact forming simulation is presented.To this end a FE-code applicable to use the inverse mechanical formulation is coupled with the commercial software MSC.Mentat. In the inverse computation the contact problem is approximated by displacement control. |
