• This paper deals with the thermal stress analysis of an infinite circular elastic cylinder heated on the surface axisymmetrically by heat sources, which move at a constant velocity in the axial direction. The underlying heat conduction problem, as well as the associated thermoelastic problem, is attacked with the aid of the exponential Fourier transform on the assumption that the cylinder is homogeneous and isotropic with respect to both its thermal and elastic response and that the temperature distribution of the surface is prescribed. The solutions for the temperature and stress distributions are obtained in the form of infinite integrals. Numerical examples, which are carried out for two specific distributions of the surface temperature, show a marked influence of the velocity of the heat sources on the distribution of the thermal stresses.
