On one effictive model of a fractured medium
L. A. Molotkov St. Petersburg Department of V. A. Steklov Institute of Mathematics, Russian Academy of Sciences
Abstract:
The homogeneous isotropic elastic medium, interested by three systems of fractures on which jumps of stresses are proportional to displacements, is considered. The effective model of this medium is described by equations differing from the corresponding equations of the elastic medium by additional terms. On the basis of the equations of the effective model the wave field excited by some point source is established. The investigation of the integral representation of the wave field shows that the velocities of the longitudinal and transversal waves and of the Rayleigh wave are functions of frequency and wave numbers. The formulas for the phase and group velocites of these waves are derived.
