-
摘要: 本文首先应用逐步加载法将具有硬中心的开顶扁球壳在均布载荷作用下的非线性微分方程组线性化,然后利用样条配点法解线性微分方程组,得到了临界载荷的数值.Abstract: In this paper,to begin with.the nonlinear differential equations of a truncaled shallow spherical shell with variable thickness under uniformal distributed load are linearized by step-by-step loading method.The linear differential equations can be solved by spline collocanon method.Critical loads have been obtained accordingly.
