The paper proposes a new approach to the problem of stability of imperfect shells, which is used to assess their quality. Numerical results for ribbed shells with initial deflections of two types are presented. Comparing them allows assessing the quality of shells. The approach is used to determine the minimum critical load of a smooth shell, which was experimentally examined before  相似文献

The buckling problem for longitudinally corrugated cylindrical shells under external pressure is solved. The solution makes practically exact allowance for the geometry and buckling modes of the shell. The inaccuracy of the results is due to the assumption that the subcritical state is momentless. Shells consisting of cylindrical panels of smaller radius and noncircular shells with sinusoidal corrugations are analyzed for stability. The practical applicability of such shells is demonstrated __________ Translated from Prikladnaya Mekhanika, Vol. 43, No. 11, pp. 66–79, October 2007.  相似文献
