| Summary: | The research of wave propagation in elastic wedge plate revealed new acoustic effects near the edge unknown in the technical literature. At surface wave movement in this area the acoustic field is a continuously restructured and spatial wave radiation occurs. When reaching the edge the surface wave rate falls to zero, but in the opposite direction the wave gains velocity. All these facts identify a new physical phenomenon: the inverse wave in the wedge plate occurs not due to reflection from an edge in the classic sense, but because of wave flow compression. Occurring at falling and reverse fluctuations impose the standing nonuniform wave is formed of the displacements of small amplitude. The wave motion of original physical nature occurs along the wedge edge. |
