✦ Synopsis

Comparisons of the laboratory physical modeling experiment and the finite element numerical simulation of the physical modeling experiment of wave propagation in an acoustic/elastic coupled medium, reveal that the finite element numerical simulation of the physical modeling experiment, when an elastic medium is modeled as an acoustic medium, is definitely inferior than that, when an elastic medium is modeled actually as an elastic medium. The elasticity of an acoustic/elastic coupled medium, as expected, has a pronounced influence on the shear wave conversion and propagation; in turn, the characteristics of wave forms and arrival events involve both the compressional and shear waves.

These findings may bear significant implications of whether the elastic property of the ocean bottom plays an important role in the long range sound transmission in oceans.
