摘要: 利用大型仿真软件MATLAB编程和矩阵计算的优点,使用一种全新的方法来进行有限元分析.结合一个实例, 利用编写的M函数文件,求得节点的位移、反力,并绘出单元的剪力图和弯矩图,经验证后,证明该方法行之有效.

关键词: MATLAB, 有限元, 刚度矩阵, M函数文件

Abstract: By the programming and the matrix representation merit of the large-scale simulation software MATLAB,the finite element analysis is carried on with a brand-new method.The displacement and reaction of the pitch point are obtained through compilation M function document based on an example,and the shear diagram and the bending-moment diagram of the ele- ment are drawn.The confirmation proves this method effective.

Key words: MATLAB, finite element, rigidity matrix, Mfunction document
