Reflection of acoustic wave from the elastic seabed with an overlying gassy poroelastic layer

Acoustic wave propagation in gassy porous marine sediments: The rheological and the elastic effects.

The preceding paper in this series [Mantouka, Dogan, White, and Leighton, J. Acoust. Soc. Am. 140, 274-282 (2016)] presented a nonlinear model for acoustic propagation in gassy marine sediments, the baseline for which was established by Leighton [Geo. Res. Lett. 34, L17607 (2007)]. The current paper aims further advancement on those two studies by demonstrating the particular effects of the sed...

An efficient Wave Based Method for axisymmetric acoustic-poroelastic problems

The most commonly used prediction techniques to study the steady state behaviour of coupled acousticporoelastic problems are based on the Finite Element Method. However, due to the large computational load when frequency increases, these methods are restricted to low frequency problems. Recently, a Wave Based Method was developed to tackle this type of problems in a more efficient way. The meth...

Love Wave Propagation in a Fiber-reinforced Layer with Corrugated Boundaries Overlying Heterogeneous Half-space

Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...
