Coupled Thermal Stress in Solid Cylinder due to Limited Heating

Abstract

The present paper deals with temperature and stress in a solid cylinder due to limited heating. Thermomechanical coupling was taken into account in the analysis. Numerical calculations were performed for various heating time and thermomechanical coupling parameters.
The results obtained are summarized as follows:
(1) The coupled temperature at the surface after a limited heating time becomes higher than the uncoupled one.
(2) A long heating time causes large axial tensile stress at the surface after the limited heating time. The coupled axial tensile stress is smaller than the uncoupled one.
(3) Any maximum axial tensile stress at the surface after a limited heating time does not become larger than the maximum axial compressive stress at the surface during the heating period.
