Modelling of Stamping of DP Steel Automotive Part Accounting for the Effect of Hard Components in the Microstructure
The paper presents simulations of the manufacturing of the automotive part,which has high influence on improvement of passengers safety.Two approaches to the Finite Element (FE) modelling of stamping of a part that provides extra stiffening of construction subassemblies in the back of a car were considered.The first is conventional simulation,which assumes that the material is a continuum with flow stress model and anisotropy coefficients determined from the tensile tests.In the second approach two-phase microstructure of the DP steel is accounted for in simulations.The FE2 method,which belongs to upscaling techniques,is used.Representative Volume Element (RVE),which is the basis of the upscaling approach and reflects the real microstructure,was obtained by the image analysis of the micrograph of the DP steel.However,since FE2 simulations with the real picture of the microstructure in the micro scale,are extremely time consuming,the idea of the Statistically Similar Representative Volume Element (SSRVE) was applied.SSRVE obtained for the DP steel,used for production of automotive part,is presented in the paper in the form of 3D inclusion.The macro scale model of the simulated part is described in details,as well as the results obtained for macro and micro-macro simulations.
