 note = {application/pdf, Propagations of axial, flexural and torsional stress waves in a two concentrically layered cylinder; an inner solid an outer annular cylinders of different elastic moduli each other, is investigated as an eigen value problem of the coefficients matrices of boundary conditions which are derived from the solution of dynamic equations of cylindrical coordinates by means of Hankel transforms. The discussions are around the variations of wave velocity with the charge of ratio between wave length and the diameter of the outer cylinder, and the wave modes for various wave length. The numerical calculations are performed for several ratio of the diameter of the cylinders, and elastic moduli for solid and cylinder.},
