Generation of Love Wave in a Media with Temperature Dependent Properties Over a Heterogeneous Substratum
The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semi-infinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent. The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Lo...
متن کاملLove waves in a piezoelectric layered structure
Consider a layer made of a m3m insulator crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For a Xor Y -cut of the substrate, a Love wave can propagate in the resulting structure and the corresponding dispersion equation is derived analytically. It turns out that a fully explicit treatment can also be conducted in the case of a ...
متن کاملSimulation of P-Wave Propagation in a Heterogeneous Spherical Earth: I. Numerical Method
To be able to simulate P-wave propagation in a heterogeneous spherical Earth, we solve the acoustic wave equation in spherical coordinates numerically for axi-symmetric media. We employ a high-order nite-diierence scheme which allows us to simulate arbitrary heterogeneous structures with wavelengths as small as 10km. A standard regular gridding in spherical coordinates leads to a continuously d...
متن کاملLove 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...
