Abstract

The effective thermoelastic properties of composites filled with cylindrical nanofillers are evaluated using the statistical continuum theory of strong contrast. In terms of aspect ratio, the inclusions vary across a wide range from nanoplatelets to nanowires. As nanostructure descriptors, the statistical two-point correlation functions are calculated using the Monte Carlo method. Then the three-point correlation functions are estimated via an innovative technique. The resulting quadruple and sextuple integrals are calculated using the Monte Carlo integration. The final complicated tensorial equations of the elastic part are solved by trial and error. Finally, the similarities between the effective elastic and thermal properties as well as their visual symmetries are discussed.
