Abstract : The elastic plastic stress distribution is obtained for a long, thick walled cylinder subjected to radially symmetric external pressure and heating. The stress distribution is also calculated using the approximations of thin walled shell theory, b t it is found that this solution could, in certain cases, lead to serious discrepancies even for thin walled shells. The buckling load of the partially plastic cylinder is computed by an energy method using the buckling theory of thin walled shells. It is shown that partial yielding due to the combination f pressure and temperature can appreciably lower the buckling strength from the fully elastic value. (Author)
