| Abstract | ||
| The present paper deals with the axisymmetric deformation in homogeneous isotropic thermoelastic solid with two temperatures, with and without energy dissipation using modified couple stress theory. The effect of energy dissipation and two temperature is studied due to the concentrated normal force, normal force over the circular region, thermal point source and thermal source over the circular region. The Laplace and Hankel transform techniques have been used to find the solution to the problem. The displacement components, conductive temperature distribution, stress components and couple stress are computed in the transformed domain and further calculated in the physical domain using numerical inversion techniques. Effects of two temperature and energy dissipation on the conductive temperature, stress components and couple stress are depicted graphically. | ||
