有限元的理论和方法发展非常迅速。然而,不管是采用何种单元,在解题过程中都免不了要联立求解一组线性代数方程组,如若节点较多,机器容量较小的话,就会对解题带来一定的困难(当然,从计算方法的角度出发,可以采用各种有效的方法来改进)。本文是基于这洋一种思路:类似结构力学中的“力矩分配法”那样,不去直接求解由力法、
The theory and method of finite element development is very rapid. However, no matter which unit is used, it is inevitable that in the process of solving the problem, a set of linear algebraic equations will be solved together. If there are more nodes and the capacity of the machine is smaller, it will bring certain difficulties to solving problems (of course. From the point of view of the calculation method, various effective methods can be used to improve). This article is based on the idea of the ocean: like the “moment distribution method” in structural mechanics, it does not directly solve the force method,
