In this paper, a new method, exact element method for constructing finite element, is presented.
本文提出构造有限单元的新方法——精确有限元法。
NASTRAN, and presents a handy and exact correction method, to eliminate the warp of moment of the deflective girder in the FEM results effectively, and get the preferable element forces in the girder.
NASTRAN中偏心梁有限元计算结果的弯矩偏差现象，并给出了一种简便、准确的修正方法，能够有效地消除计算结果中偏心梁元的弯矩偏差，并得到较为理想的梁元内力。
The appearance of the finite element method would provide us a way to solve it. We can approximate the true situation as long as the division is exact and units are small enough.
有限元法的出现，给我们解决这一问题提供了有效的途径，只要边界条件足够准确、单元足够小就可以逼近真实情况。
