Antiplane wave scattering on tunnel cylindrical cavities with fixed inclusions of radial cross-section in orthotropic body

It is presented numerical-analytical technique for solving longitudinal shear wave diffraction scattering on tunnel cylindrical cavities in anisotropic orthorhombic system elastic massif with fixed inclusions of radial cross-section problems. Proposed method is based on generalized metaharmonic equation integration in affinetransformed coordinates. Amplitude wave field characteristics are presented by series with undefined coefficients on basic particular solutions. These solutions are expressed through cylindrical functions of polar coordinate in affinetransformed areas. Considered edge problems are reduced to infinite linear algebraic system analysis by using the method of least squares. Results of numerical and qualitative analysis for constructed solutions and wave field characteristics studies, when problem parameters are varied, are presented.
