| 摘 要： | 著名的唐乃尔(Donnell)——穆什塔利的简化壳体理论只能较精确地适用于较短圆柱壳稳定性计算.其近似性误差随长度与半径之比的增加而增大.本文考虑了横向切力的影响,对非完善型圆柱壳体推导了几何非线性理论的基本方程,建立了对各种长度半径比的圆柱壳体稳定性均适用的修正理论.

| Abstract: | Famous Donnell's and theories of shell can only be used in the stability of shorter cylindrical shells. In their theories, the errors increase with the inorease of L/R (L-Length of circular cylindrical shell; R-Radius). This paper takes into account the transverse shearing forces and presents the imperfect cylindrical shells with a basic equation of the nonlinear theory. According to this revised theory, a computational scheme suited to various cylindrical shell length, radius and thickness has been developed. |
