| 摘 要： | 本文提出分析圆环壳屈曲的一种渐近解析方法,由Sanders非线性平衡方程和壳中面变形协调方程推导出静水外压下环壳的稳定方程,求出了方程的渐近解,理论计算的临界压力值与Fishlowitz的实验结果符合良好,并研究了屈曲前非线性变形对临界载荷的影响。

| Abstract: | Stability equations for toroidal shells under hydrostatic pressure are derived from Sanders' nonlinear equations of equilibrium and the equation of compatibility. They are solved by the use of asymptotic method. Theoretically predicted buckling pressures are in good agreement with experimental results obtained by Fishlowitz. The effect of prebuckling deflection on critical loads is investigated. |
