Scattering of pressure waves by limited subject with internal stresses
Sournev V. B., Islamgaliev D. V.
The article describes the mathematical model of scattering of pressure (seismic) waves by prestressed limited heterogeneity. We derived the integral equations that generalize known equations of the scattering theory of pressure waves in the case of prestressed heterogeneity, without using the general wave theory in a prestressed area. The algorithm for the numerical simulation of elastic waves scattering implements to obtained integral equations.
Keywords: heterogeneous medium; scattering theory; elastic waves; integral equations; prestresses.
