2-D PROBLEM OF GENERALIZED THERMOELASTIC POROUS MEDIA UNDER THE EFFECT OF INITIAL STRESS AND MICROTEMPERATURES

A general solution has been obtained to the field equations of thermoelastic porous media in the context of Lord and Shulman theory under the initial stress and microtemperatures effect. The effect of thermal relaxation time and initial stress on the displacements, the microtemperature vector, the temperature distribution, the normal stress, the changes in the volume fraction field, and the heat flux moments have been depicted graphically in the Lord and Shulman theory (L-S) and coupled theory (CT) of thermoelasticity with voids and microtemperatures. The normal mode analysis is used to obtain the exact expressions for the considered variables. Some particular cases are also deduced from the present investigation.
