Multiple Scattering Using Parallel Volume Integral Equation Method: Interaction of SH Waves with Multiple Multilayered Anisotropic Elliptical Inclusions

Figure 26

Real and imaginary parts of the displacement component in -axis, , at the interface for (a) the single orthotropic elliptical (90°) inclusion (#2), (b) the central inclusion with a hexagonal packing of seven orthotropic elliptical (90°) inclusions (#2), where , and (c) the central inclusion with a hexagonal packing of seven orthotropic elliptical (90°) inclusions (#2), where . The frequencies used are = 3.14, 5.03, and 7.85, where is wavenumber in the unbounded isotropic matrix and is the major radius of each elliptical inclusion. The inclusion cited represents the orthotropic inclusion #2 in Table 4.
