This paper is addressed to the Love wave propagation in a layered piezoelectric structure immersed in a viscous fluid. The layered piezoelectric structure consists of an isotropic layer and a relatively thicker transversely isotropic piezoelectric substrate. The velocity of the Love waves changes due to the presence of the viscous fluid. The exact theory is accurate but not convenient to apply because it is generally difficult to get an explicit relation between the quantities we interest. In this paper, the perturbation approach is applied to obtain the explicit relations for the phase velocity and attenuation of Love waves. The result is useful for the measurement of the viscosity and mass density in Love wave sensors.

Plane contact problems of an elastic, homogeneous, and isotropic layer supported by a Winkler foundation are studied in this paper. The elastic layer has a finite depth and infinite in-plane dimensions. The upper surface of the layer is in plane contact with a rigid indenter. The particular applications studied in this paper are formulated by first providing the solution for a line load. For the case of a rigid cylinder, the upper portion of the load deflection response is modeled using beam theory with wrapping. The contact pressure distributions for the relatively flexible foundation cases can be accurately determined from the wrapping theory.

Dispersion of Love waves is studied in a fibre-reinforced layer resting on monoclinic half-space. The wave velocity equation has been obtained for a fiber-reinforced layer resting on monoclinic half space. Shear wave velocity ratio curve for Love waves has been shown graphically for fibre reinforced material layer resting on various monoclinic half-spaces. In a similar way, shear wave velocity ratio curve for Love waves has been plotted for an isotropic layer resting on various monoclinic half-spaces. From these curves, it has been observed that the curves are of similar type for a fibre reinforced layer resting on monoclinic half-spaces, and the shear wave velocity ratio ranges from 1.14 to 7.19, whereas for the case isotropic layer, this range varies from 1.0 to 2.19.

This paper studies the possibility of propagation of Love waves in a nonhomogeneous internal stratum of finite depth lying between two semi‐infinite isotropic media in two different cases. In one case the rigidity and density vary as [Formula: see text] and in the other case as [Formula: see text], where λ is a constant and z is the depth measured from the common interface of the upper medium and the internal stratum.
