Precisely understanding material properties and characteristics is an essential requirement in order to achieve reliable forming simulation results. Depending on the forming process, different properties of the sheet material – hardening, anisotropy, temperature, strain rate or damage behavior – will be desired and each of these properties needs to be characterized and utilized in the material model. Here at the Fraunhofer IWM, we perform the following testing for the experimental characterization of sheet metal materials:
(More about microstructure analysis at the Fraunhofer IWM)
(More about residual-stress analysis at the Fraunhofer IWM)
(More about Tribology at the Fraunhofer IWM)
(More about thermophysical characterization at the Fraunhofer IWM)
Appropriate material models are selected based on the experimental data; parameters are then adjusted and transferred into the numerical simulation.
