这是一个平面桁架结构的通用有限元程序分析，将原始数据（节点坐标、连接关系、材料几何参数边界条件）存储，利用以上数据编辑Matlab 程序计算桁架的应力、应变、位移分量，将所得数据存入二进制文档，并且研究当固定单胞数目时，怎么修改设计，在不明显增加质量时，降低最大应力杆的应力。 -This is a general-purpose finite element program planar truss structure analysis, the raw data (node ​

运用MATLAB实现大型复杂平面有限元问题的位移、应力、应变等功能的实现 -These codes are intent to be used for calculating the displacement, stress, strain in complex, large plane problems in Matlab rather than in FEM softwares.

以三角形网格为实例，采用有限元法计算悬臂梁的应力分布(Taking the triangular mesh as an example, the stress distribution of the cantilever beam is calculated by the finite element method)

Matlab编写的梁杆单元的有限元分析，分析应力、应变。(The finite element analysis of beam column element written in Matlab is used to analyze stress and strain.)
