Abstract:
The application of simulation models in sheet metal forming in the automotive industry has proven to be beneficial to reduce tool costs at the designing stage and for optimising current processes. Moreover, it is a promising tool for a material supplier to optimise material choice and development for both its final application and its forming capability. The present practice requires a high predictive value of these simulations. A first stage is to implement the improved material models which describe this single strain path behaviour in a better way. Results are compared with predictions using Marciniak-Kuczinsky-analysis with both the new material model and the conventional material model. Finally, the validation on real pressed products is shown by comparing simulation results using different material models with the experimental data. The test required to measure the required material data are described in this conference paper.
