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 creep buckling occurs. Two types of creep buckling are considered in the present analysis. One is the axisymmetric mode of creep buckling due to quasi-static instability. The other is the asymmetric mode of creep buckling due to bifurcation. The effects of internal or external pressure on creep buckling are made clear by the present analysis.
