Abstract
On the basis of a fractal model the macroscopic elastic properties of an in homogeneous medium with random structure have been determined. It is shown that if the ratio of the bulk moduli of the phases K-2/K-1--> 0, then the p ercolation threshold p(c) the Poisson coefficient is equal to 0.2. A study of the behavior of a two-phase medium with negative Poisson coefficient is carried out. (C) 1999 American Institute of Physics. [S1063-7834(99)00912-0 ].
