We obtained the general expressions of displacement and stress components on the thermal stress, in terms of stress function, of cylindrical bodies in case of axial symmetry, which are expressed in different forms according to the steadiness and non-steadiness of the temperature. Several problems have been solved in terms of examples and the conclusions found are as follows : an usual solution in case of circular disc has been proved to be incorrect (Udoguchi's solution is correct as long as the temperature is steady) and, moreover, the exact solution in case of heating up gives an instantaneous maximum stress which is greater than the stress at steady state and sometimes amounts to several times as large a stress as that at steady state. This explains the danger of failure of a disc at sudden heating up.
