Abstract
The three-dimensional problem of wave’s propagation in an elastic layer is considered. On planes limiting a layer, the conditions of equality to zero of a normal stress, one of the tangent stresses and one of the tangent displacеments are given. For phase speed of symmetric and antisymmetric vibrations the characteristic equations are received. The limiting cases are considered: length of a wave is very great and very small in comparison with thickness of the layer. The numerical accounts for phase speed of the wave are given.
