|Abstract:||Analytical solutions with several new features have been developed for temperature and elastic thermal stress distributions for a hollow circular cylinder under sinusoidal thermal transient loading at the inner surface. The approach uses a finite Hankel transform in a general form for any transient thermal loading for a hollow cylinder. Using the properties of Bessel functions, an analytical solution for temperature distribution through wall thickness was derived for a special case of sinusoidal transient thermal loading on inner pipe surface. The solutions for associated thermal stress components were developed by means of the displacement technique. To the authors’ knowledge, this is first time a complete set of such analytical expressions has been openly published.|
