Abstract
We have analyzed the thermal expansion mismatch stresses at the vicinity of a cylindrical ceramic-metal compressive joint in which the thermal expansion coefficient of the ceramic member is smaller than that of the metal member. The results of the calculation predict the presence of a large tensile axial stress at the surface of the ceramic member and agree quantitatively with those by the finite element method. Contrarily, in this paper, we treat a tensile cylindrical joint in which the thermal expansion coefficient of the ceramic member is larger than that of the metal member. In this joint, a tensile radial stress or a tensile tangential stress plays a major role in the ceramic member. We discuss their distribution and axial variation in detail.
