Figure 1   schematic illustration of P wave diffraction by a spherical inclusion.
Figure 2   Sketch of dynamic generalized self-consistent model.
Figure  3  depicts  the  variations  in  normalized  phase  velocity  and  attenuation  of  the  longitudinal  average wave in terms of dimensionless wave number and volume fraction of soft, stiff, light and  heavy inclusions using the dynamic generalized
Figure 4f shows the parameter in terms of volume concentration. It can be seen that increasing  the  volume  fraction  does  not  show  any  variation  in  the  effective  density  of  composite  materials  which contain soft and stiff particles
