(a) Effective longitudinal sound velocity of the TE/TiO2 nanocomposites at varying weight fraction of the TiO2 nanoparticles. The Wood’s law fitting based on eq 2 was conducted with two sets of adjustable values of the density and sound velocity of TiO2 (red line: ρTiO2 = 870 kg/m3 and cL, TiO2 = 3650 m/s; blue line: ρTiO2 = 3900 kg/m3 and cL, TiO2 = 8880 m/s). (b) Computed effective elastic longitudinal modulus of the TE/TiO2 nanocomposites as a function of the weight fraction of the TiO2 nanoparticles (see text).
