摘要：

On the basis of a fractal model the macroscopic elastic properties of an inhomogeneous 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 percolation 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].
