TI - Rayleigh Waves Propagation in an Infinite Rotating Thermoelastic Cylinder T2 - Computers, Materials \& Continua PY - 2021 VL - 67 IS - 2 SN - 1546-2226 AB - In this paper, we investigated the inuence of rotating half-space on the propagation of Rayleigh waves in a homogeneous isotropic, generalized thermo-elastic body, subject to the boundary conditions that the surface is traction free. In addition, it is subject to insulating thermal conduction. A general solution is obtained by using Lame’ potential’s and Hankel transform. The dispersion equations has been derived separately for two types of Rayleigh wave propagation properties by solving the equations of motion with appropriate boundary conditions. It is observed that the rotation, frequency and r exert some influence in the homogeneous isotropic medium due to propagation of Rayleigh waves. The frequency equation has been derived of homogeneous properties by solving the equations of motion with appropriate boundary conditions. It has been found that the frequency equation of waves contains a term involving the rotating. Therefore, the phase velocity of Rayleigh waves changes with respect to this rotating. When the rotating vanishes, the derived frequency equation reduces to that obtained in classical generalized thermo-elastic case which includes the relaxation time of heat conduction. In order to illustrate the analytical development, the numerical solution is carried out and computer simulated results in respect of Rayleigh wave velocity and attenuation coefficient are presented graphysically. A comparative and remarkable study has been carried out through various graphs to deliberate the consequences of different parameter on the frequency equation. The obtained results can be very useful in the design and optimization of Rayleigh wave.
