โœฆ Synopsis

The propagation of a shear surface wave (SSW) along the interface of an elastic half-space liquid and micropolar half-space is considered. The phase velocity of the wave and its attenuation constant are determined. It is shown that a SSW at the interface of a solid and a micropolar liquid propagates almost without dispersion, unlike a wave at the interface of a solid and a viscous Newtonian liquid in which the dispersion is noticeable at high frequencies. The attenuation of the SSW is considerably weaker in the first case than the second. The attenuation constant decreases as the boundary viscosity increases.

The stresses and displacements near the end of a crack situated at the interface of an elastic half-plane bonded to a rigid body under uniform tension at infinity are analysed. The solution is obtained by the Fourier transforms and in the form of a tri-gonometrical series. Because of forming a proce

Reflection and transmission phenomena of a plane longitudinal displacement wave impinging obliquely at a plane interface between a micropolar elastic solid half-space and a chiral elastic solid half-space are investigated. The incident wave is assumed to be striking at the plane interface after prop
