Effective elastic modulus versus nanoparticle size calculated for an RVE. Size and shape convergence of the effective elastic modulus calculated from the triaxial stress of an RVE at the center of the nanoparticles. Two shapes, (a, b) truncated octahedron and (c, d) rhombicuboctahedron, were teted in two crystallographic orientations with respect to the direction of the load, (a, c) correspond to the {111} orientation and (b, d) to the {100} orientation. The bulk values are shown as dashed lines and the effective elastic moduli calculated for the entire nanoparticles from the triaxial state are shown as solid stars
