摘要
在编制有关板壳的大型计算程序中,以最小势能原理为基础,用张量理论对非线性基本理论进行了分析。在形成刚度矩阵时,避开非线性问题的直接迭代法和切线模数增量法中不易得到的应力及变形情况,直接导出刚度矩阵。
In drawing up the large-sized calculation program of sheet metal, the basic theory of unlinear has been analysed by the tensor theory based on minimum potential energy principle. During the formation of rigidity matrix, it is necessary to avoid the direct alternative of unlinear and those strees and deformation that are not easy to get in the increment of liner pattern in order to derive the rigidity matrix directly.
