Fig. 6 Correlation functions of the second(a) and fourth (b) order, a=10 mm, p=0.15 and an experimental graph of the force dependence on displacement for a structure with the inclusion form of an icosahedron (c).

Although there is obviously some error between the computational and experimental results, one can still observe a clear trend towards changes in the effective modulus of elasticity, which are caused by the shape of inclusions – both for the calculated and experimental values obtained for the effective modulus of elasticity (Table 1). The experimental modulus of elasticity for each sample was calculated using the construction of tangents (Fig. 6c).
