Transient thermal stresses are investigated in a transversely isotropic finite circular cylinder inserted into a rigid heated circular ring. The temperature and thermal stress fields are analyzed by means of the Laplace transform and the transversely isotropic potential functions method, respectively. The radial, hoop and axial thermal stresses have singularities at the end of the contacted rigid ring on the cylindrical surface. For that, factors are defined to evaluate the singularities of these stresses. Numerical calculations of these factors were carried out for transversely isotropic graphite. The effects of transverse isotropy, Biot numbers and the length of the circular cylinder on the factors are examined.
