Venture The strategic innovation programme for Metallic material

Important results from the project

The project has achieved the goals in studying material properties and material models for the newly developed materials H800, FDX27 and Ducol 1400. Calibration of an advanced friction model has been done, a conference paper have been published on the subject. Numerical and experimental studies have been made with differences between tool materials , triboligical conditions and rigid, respectively. elastic assumptions were analyzed. Overall, new steps have been taken within virtual spotting. Industrial application should be studied in future projects.

Expected long term effects

Overall, new steps have been taken to be able to perform virtual spotting with partial steps such as the advanced friction model, a method for modeling elastic tool deformations and compensation of thinning / thickening. Future steps relate to refining the advanced friction model in order to also take into account deformation rates and temperature increase as well as studies of forming processes for an industrial case where evaluation of virtual spotting can be done with the aim of taking the method to a higher TRL level, prior to industrial implementation.

Approach and implementation

The project has been carried out within various delimited work packages such as; study and calibration of material properties and plasticity model; FE modeling of forming with rigid or elastic tools and validating forming experiments. The project´s various work packages have contributed to the development of the method for virtual spotting where the various components now can be applied in industrial cases.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
