摘要
本文对圆柱扁壳的非线性动力响应的问题,利用加权残值法的子域方法将唐奈尔方程转化成时间因子作为未知函数的控制方程,运用样条配点法将时间域分成若干段,且保证在每一时间段均连续,将算例结果与有关文献比较的同时,还运用ODE SOLVER-COLSYS程序作数值比较。
In this paper, the nonlinear dynamic response of circular cylindrical shallow shells subjected to impulsive load is analysed. The Donnell governing equations are solved by applying spline weighted residuals method. The results of computation are in good agreement with the results computed by using ODE SOLVER-COLSYS.
