Macroscopic stress–strain responses of the two-phase polycrystalline unit cells under uniaxial tension as predicted by MFDM-EVP-FFT, with grain size \( d_{g} = 1.24\;\upmu{\text{m}} \) and interspacing distances \( l_{p} \) ranging from 0.33 to 1 µm (solid lines), and \( d_{g} = 6.20\;\upmu{\text{m}} \) and interspacing distances \( l_{p} \) ranging from 1.55 to 5 µm (dotted lines). Black dotted and plain lines give the tensile response of polycrystalline unit cells without particles, with respective grain sizes of \( {d}_{{g}} = 6.20\;\upmu{\text{m}} \) and \( {d}_{{g}} = 1.24\;\upmu{\text{m}} \)
