The Debye’s Potentials Utilization in the Three-Dimensional Problems of the Radiation and Propagation of the Elastic Waves

Are studied internal and external tasks of radiation of a sound by the elastic bodies, exciting by the harmonic point source, imitating turbulent pulsation of a flow of a liquid. The angular characteristics of radiation of a hollow spheroidal shell are calculated. The characteristic equations of the axial three-dimensional flexural waves in the hollow cylindrical shell and cylindrical bar are received with the help of Debye’s potentials. The phase velocities of the various forms of these waves for shells and for cylindrical bar are calculated.
