The material is assumed to be Available online homogeneous and isotropic with temperature-independent thermal properties. The standard 24 August 2014 Keywords method of separation of variables is used for solving the problem with time-independent Non-Fourier Conduction boundary conditions and the Duhamel integral is used for applying the time-dependency. The Analytical Solution results show the wave behavior of Non-Fourier thermal stresses and higher oscillation Cylindrical Coordinate amplitude in comparison with Fourier one. The developed analytic answer can be applied for Harmonic Boundary Conditions modeling cylindrical shell of nuclear rod and can be applied as a benchmark to validate the other numerical solutions. 2014 Growing Science Ltd.
