Combining Corus and ESI Group expertise, this partnership will help automotive designers and engineers to significantly improve the accuracy of formability analysis predictions and press stamping evaluations.
Using computer-aided tools to help reduce the cost and time necessary for new vehicle development and improve manufacturing processes is not new.
Formability analysis tools are currently used to predict material behaviour to simulate what happens when sheet material is stamped into a three-dimensional part, such as a body panel.
However, as carmakers increasingly use advanced high strength steels and aluminium alloys, existing material simulation tools – largely based on data from mild strength steels and featuring relatively simple models – are becoming more and more inadequate for the latest simulation requirements, especially panel quality and tolerance control.
Corus has developed the unique Corus-Vegter model, which incorporates advanced understanding of sheet metal behaviour during deformation in response to the need from the global automotive industry for a model that can accurately predict the behaviour of more modern and widely used materials. Over the last two years, Corus has worked closely with ESI Group to implement the model in the sheet metal forming simulation software package.
The model has been validated on a full-scale automotive part in collaboration with Renault.
