The Parallel Volume Integral Equation Method (PVIEM) is applied for the analysis of elastic wave scattering problems in an unbounded isotropic solid containing various types of a multilayered anisotropic inclusion. It should be noted that this numerical method does not require the use of the Green׳s function for the multilayered anisotropic inclusion-only the Green׳s function for the unbounded isotropic matrix is needed. This method can also be applied to solve general elastodynamic problems involving arbitrary shape and number of inhomogeneous and/or multilayered anisotropic inclusions. A detailed analysis of the SH wave scattering is presented for various types of a multilayered orthotropic inclusion. Numerical results are presented for the displacement and stress fields at the interfaces of the multilayered inclusion in a broad frequency range. Parallel volume integral equation method as a pioneer of numerical analysis enables us to investigate the effects of single/multiple layer(s), multilayer׳s shape and geometry, isotropy/anisotropy, and softness/hardness of the multilayered anisotropic inclusion on displacements and stresses at the interfaces of the inclusion.
