In the analysis, plastic strain is included in addition to elastic and creep strains. Not only the axisymmetric mode but also the bifurcation mode are considered in the creep buckling analysis. Three types of plastic constitutive equation that is, the flow theory the modified flow theory, and the deformation theory are used to predict the critical time of creep buckling. It is found from the analysis that the critical times of the modified flow theory and the deformation theory are smaller than that of the flow theory.抄録：英語フィールド
