Advanced thermo-viscoplastic material model coupled with continuous integration of damage parameter was combined with dedicated friction model in a thermo-mechanical FE simulation of HFQ(R) forming of high strength aluminium alloy. The friction model was setup to capture complex tribologic response of hot and dry aluminium sheets formed on cold and lubricated tools. Friction was assumed as a function of temperature, contact pressure and sliding distance. This paper presents results of correlation of the simulation results with experimental measurements of thermo-mechanically formed downscaled B-pillar parts. The forming trials were performed on a dedicated aluminium hot forming line using especially designed blank shapes and forming conditions to introduce failures in specific locations. Thickness and shape measurements where then correlated to finite element simulation performed in PAM-STAMP 2019 with friction and material models implemented in HFQ® Module.
