摘要：

The elastic-plastic response of a metal-matrix composite (MMC) consisting of a AA6061-T6 aluminium matrix reinforced with 20 vol.% Al2O3 particles was modeled using the finite element method. As input for the model, a real three-dimensional (3D) microstructure obtained by holotomography was used. The macroscopic behavior of the composite was obtained by multi-scale modeling based on a window-averaging and extrapolation technique. Model compression stress-strain curves obtained for a cubical volume of edge length 9-10 times larger than the two-point correlation length of the matrix show satisfactory agreement with experimental data.
