Dynamical behavior of generalized thermoelastic diffusion with two relaxation times in frequency domain
Nidhi Sharma, Rajneesh Kumar and Paras Ram

 
Abstract
    A general solution to the field equations of homogeneous isotropic generalized thermoelastic diffusion with two relaxation times (Green and Lindsay theory) has been obtained using the Fourier
transform. Assuming the disturbances to be harmonically time.dependent, the transformed solution is obtained in the frequency domain. The application of a time harmonic concentrated and distributed loads
have been considered to show the utility of the solution obtained. The transformed components of displacement, stress, temperature distribution and chemical potential distribution are inverted numerically, using a numerical inversion technique. Effect of diffusion on the resulting expressions have been depicted graphically for Green and Lindsay (G-L) and coupled (C-T) theories of thermoelasticity.
 
Key Words
    generalized thermoelastic diffusion; time harmonic; concentrated and distributed loads; fourier transform.
