ABSTRACT: This paper deals with the creep buckling of a circular cylindrical shell subjected to both axial compression and internal or external pressure. The finite element method is applied to a creep deformation analysis to obtain the critical time when the creep buckling occurs. Two types of creep buckling are considered in the present analysis. One is the axisymmetric mode of creep buckling due to the quasi-static instability. The other is the asymmetric mode of creep buckling due to the bifurcation. The effects of internal or external pressure on the creep buckling are clarified by the present analysis.
