Abstract
A micromechanical modelling based approach by means of a Representative Volume Element (RVE) was employed to predict the flow behaviour and plastic strain of DP600 steel, produced by WISCO. Macroscopic modelling of a classical Bending-Under-Tension (BUT) experiment was employed to acquire strain deformation, and thus the following microscopic modelling was implemented by considering the realistic microstructure morphology. Comparisons between macroscopic behaviour and microscopic behaviour, including strain distribution and stress distribution, were extracted for different boundary conditions of the BUT set-up. The micro–macro modelling approach increases the understanding of the steel microstructure, which will enable this microstructure to be tailored for different applications in automobile industry in the future.
