Additive model of the elasticity of nano-and microdispersed systems

To obtain the functional dependence of the rate of propagation of the sound waves in a disperse medium with solid nanoparticles of the disperse phase (for definition—in a magnetic fluid) on the volume concentration of the particles φ, we can use the ‘additive’ model of the formation of the elasticity of microheterogeneous systems proposed by V.M. Polunin [36].
