3-DIMENSIONAL MODE SHAPES FOR HIGHER-ORDER CIRCUMFERENTIAL THERMOELASTIC WAVES IN AN ANNULAR ELASTIC CYLINDER

Three-dimensional mode shapes for thermoelastic waves in an infinite a nnular elastic cylinder of arbitrary constant wall thickness are studi ed using the exact three-dimensional thermoelastic coupled equations f or the vibrations in the n = 0, 1 circumferential modes. Three-dimensi onal axial dispersion curves are presented for a range of parameters. The corresponding mode shapes and their three-dimensional equivalents are plotted so that the types of wave vibration can be identified.
