抄録

The present paper is concerned with transient thermal stresses in a transversely isotropic infinite circular cylinder inserted into a short rigid heated circular ring. This subject is a mixed boundary value problem, and may be formulated in terms of a dual-integral equation which is reduced to a simultaneous algebraic equation applying the Neumann series. The radial, hoop and axial stresses have singularities at the end of the contacted short circular ring on the cylindrical surface. The factors are defined to evaluate the singularities of the stresses, and the relations among these factors can be derived. Numerical calculations of thermal stresses were carried out for a graphite which possesses transverse isotropy, and compared with those derived under isotropic conditions.
