摘要
用修正迭代法讨论了开顶扁球壳在均布及中心集中载荷联合作用下的非线性稳定问题,得到了临界荷载的二次近似解。
In this paper,the nonlinear stability problem of a truncated shallow spherical shell under composite load is discussed by using modified iteration method.The analytic solution of the second approximation for critical buckling load has been obtained.
