An intrinsic feature of the hot stamping process, in which a hot blank is quenched and formed between water cooled dies, is the severe thermo-mechanical deformation that the blank experiences under the combined influences of non-isothermal and non-proportional loadings. This results in challenges for conventional forming limit prediction models to accurately predict material behaviour. Formability module offers a novel viscoplastic-Hosford-MK model to predict the forming limits of material under warm/hot stamping conditions and finally optimise the forming parameters.
The functional module ‘Formability’ is developed using a unique Viscoplastic-Horsford-MK model to predict failure of warm/hot-stamped part.Formability
