Elastic wave scattering by an inclusion in a multilayered medium submerged in fluid. II: Three-dimensional model (Q1805259)

The results of the three-dimensional analysis for the nonaxisymmetric problem indicate significant variation of the radial and azimuthal displacement components with the change in the azimuthal angle. Comparison of the two-dimensional [see the foregoing entry] and three- dimensional models indicates that for the harder inclusion, both the models show similar qualitative trends in the transient and steady-state responses. However, for a softer inclusion, the steady-state responses of the two models are found to differ significantly from each other.
