Outline
The accuracy of performance characterization for material has crucial influences on the numerical simulation results. In the software CAE, it generally contains the material cards of European mainstream material suppliers and a small number of domestic manufacturers, but due to different material characteristics of each manufacturer, the corresponding material card of material with the same grade shows different data distribution law as well as the criterion of yield and hardening. Thus, it is an indispensable link in such product applications as evaluation of stamping process as well as design and manufacture of mould to accurately characterize the characteristics of their own products and establish own material cards for material manufacturers. In the paper, the test scheme suitable for presenting cold stamping performance is established and data processing method is studied by taking the typical grade DC04 for cold stamping steel as the objective. Finally, the material data card for stamping simulation analysis which could accurately characterize product characteristics of Baotou Steel is developed. After adjust the working condition of stamping based on the calculation guidance of material data card, the stamping process suitable for performance characteristics of sheet matal of Baotou Steel is obtained to ensure the accuracy of simulation technology support and accurately improve the applicability of product.
