Abstract:
Using a linear formulation, the author solves the non-stationary problem of transmission of a planar unidimensional longitudinal wave of stresses through a plane-parallel visco-elastic layer of finite thickness separating two linearly elastic half-spaces with different properties. The plane wave propagating in one of the elastic half-spaces strikes the layer boundary at right angles unidimensional problem. The field in the other elastic half-space, excited as a result of multiple reflection of the fronts from the boundaries of the layer, is studied. Graphs of small displacements at a given point of elastic half-space are given.
