| 摘 要： | 本文给出两端固支的弹性圆柱壳扭转屈曲实验与理论计算结果.实验发现,对于较长的壳,其屈曲后的变形并不占据整个壳体的长度.另外在计算中仅考虑壳体的法向边界条件,而不考虑其周向和轴向边界条件,结果和Yamaki精确解以及本文实验结果相符较好,说明周向和轴向边界条件对圆柱壳的扭转屈曲影响较小.

| Abstract: | The experimental phenomenon and theoretical analysis are given for the tor-sional buckling of elastic cylindrical shells. From the experiment, it is found that the postbuckling deformation doesn't occupy the whole length when the shell is longer. In the theoretical calculation, only the normal displacement boundary condition is taken into account. By comparing the present calculation results with the accurate result of Yamaki's theory and the present experiment results, it is shown that the influence of the axial and circumference boundary condition is less important. |
