Structural-Phenomenological Models for Predicting of the Elastic Properties for High-Pore Composites

Structural-phenomenological approach for predicting of the elastic properties for high-pore composites is used. Nonlinear local-ergodic models for the elastic properties predicting are proposed. They give us narrower Voigt–Reiss results, than calculations for the linear models. Analytical solution for calculation of the correlate approximation is developed. The following approximations deal with the higher orders moment functions for the elastic properties. They do not practically affect the first approximation obtained, that is why the following approximations are not given.
