Simulation of DP-steels based on statistically similar representative volume elements and 3D EBSD data
Micrographs of a dual-phase steel obtained from a EBSD-FIB imaging are analyzed with respect to a set of statistical measures. Then the applicability of this data to the construction of statistically similar representative volume elements (SSRVEs) is discussed. These SSRVEs are obtained by minimizing a least-square functional taking into account differences of statistical measures computed for a given reference microstructure and the SSRVE, cf. . For an analysis of the mechanical response the FE2-method is used and a series of virtual experiments shows the accordance of the response of the SSRVE to the one of the reference microstructure. In order to demonstrate the performance of the proposed procedure some representative numerical examples are given.
