一、引言有限元法是随着电子计算机技术的发展而出现和发展起来的新型数值计算方法。这一方法的基础是固体力学中所熟知的能量原理。它是一种把连续体分割成有限个元素,并对这些元素集合体推导、建立其支配方程求解的方法。随着电子计算技术的发展,这一方法将越来越显示出巨大的威力。它的优点在于,对某一结构问题完善了一个计算程序之后,同类型问题的分析计算都可以较方便地进行。

I. INTRODUCTION The finite element method is a new numerical method that has appeared and developed with the development of electronic computer technology. The basis of this method is the energy principle well known in solid mechanics. It is a continuum divided into finite elements, and the derivation of these elements, the establishment of its governing equations to solve. With the development of electronic computing technology, this method will show more and more great power. The advantage of this is that after a calculation program is completed for a structural problem, the analysis and calculation of the same type of problem can be carried out more conveniently.
