Abstract
Free vibrations of strip which has general anisotropy in his plane are investigated, then one of the faces is rigidly fastened, the opposite free, or rigidly fastened. Characteristic equations for determining frequencies of free vibrations are derived by the asymptotic method. It′s proved that two types of own vibrations are arising in the strip. But in contrast to isotropic and ortotropic strips vibrations are not purely shear and purely longitudinal. The forms of own vibrations are determined. It′s shown that for each case eigenfunctions formed ortonormalized system.

The Rayleigh waves in the case of the elastically restrained boundary
The boundary of the half-space is elastically restrained in the normal or in the tangential directions. The conditions of the surface wave existence in the dependence of restrained coefficient and wave length are establi...
