In the previous paper, we demonstrated that the circumferential waves observed in the creep buckling experiments are due to the bifurcation. In the present paper, we performed the analysis of this creep buckling phenomena. We paid special attention to the effect of end boundary conditions on the critical time of creep buckling and on the bifurcation buckling mode. We found that the bifurcation buckling of a cylindrical shell with both ends simply supported occurs earlier than that of a cylindrical shell with both ends clamped. It was also found that circular cylindrical shells exhibit three types of bifurcation buckling modes, depending on the dimensions of cylindrical shell, applied load levels and end boundary conditions.抄録:英語フィールド
