Plane SH-wave response from elastic slab interposed between two different self-reinforced elastic solids

Closed form expressions of reflection and transmission coefficients are obtained when a plane SH-wave becomes incident at a uniform elastic layer interposed between two different self-reinforced elastic solid half-spaces. It is found that the reflection and transmission coefficients are strongly influenced by the reinforcement parameters of the half-spaces. Numerical computations are performed for a specific model to study the effect of reinforcement parameters and angle of incidence of the incident wave on these coefficients. Numerical study reveals that both reflection and transmission coefficients are significantly influenced by the reinforcement parameters in the entire range of angle of incidence, except at normal and grazing incidence where the effect of reinforcement parameters is found minimum. Known results of some earlier workers are reduced from the present formulations.

Transmission of plane SH-wave through a self-reinforced elastic slab sandwiched between two anisotropic inhomogeneous elastic solid half-spaces

A problem of reflection and transmission of an SH-wave through a self-reinforced elastic slab (layer) sandwiched between two transversely isotropic and inhomogeneous elastic solid half-spaces has been investigated. Formulae for reflection and refraction coefficients are obtained in a closed form and it is found that these coefficients are strongly influenced by the anisotropy and inhomogeneity of the half-spaces and on the reinforcement parameters of the sandwiched layer. These coefficients are computed for different values of heterogeneity parameters of the half-spaces and reinforcement parameters of the sandwiched layer. An effect of thickness of sandwiched layer on these coefficients is also noticed.
