Abstract :
The peculiarities of the wave propagation in the elasto-nematic heterogeneous composites are investigated. The so-called liquid crystalline rubber-like nematic elastomers (or simply nematics) are relatively new nontraditional class of materials combining the properties of classical viscoelastic solids, liquid crystals and Cosserat media. This combinations is very promising in context of medical and bio- applications, as well as in nanomechanics (as a specific matrix). In what follows we focus the attention on the acoustical properties of composites which possess the potential of applications in many areas. The recently introduced effective low frequency model of nematic medium is used. The unusual resonance effects of two kinds in coated solids are revealed and discussed.
