摘要
本文采用加权残数法中的离散型最小二乘法求圆柱形扁壳的弹塑性解,文中的方法可以用于较为复杂载荷和边界条件的圆柱形扁壳的弹塑性问题。 采用加权残数法有它独特的优点:简便、准确、迅速、工少价廉,而且非常适宜于应用微型计算机来实施。
This paper suggests the use of discrete least square method, one of the methods of weighted residuals, to analyse the elasto-plastic solution of a cylindrical shallow shell. The method presented in this paper may be uso-plastic solution of a cylindrical shallpw .shell, shallow shells with more complex loadings and boundary conditions.The use of the weighted residual method has specific advantages: simplicity; accuracy, quickness, less work and cost, very suitable to be used in micro computers in practice.
