二维线弹性有限元程序

这是一个简单的二维有限元程序。其特点如下：

1. 线弹性材料；

2. 4节点和8节点四边形等参元；

3. 接受力与位移边界条件；

使用方法：

1. 适用于有限元初学者熟悉算法；

2. 自带输入文件。程序输出结果文件，用户需要自己进行可视化后处理；

3. 程序内有详细解释。

-Finite element method for 2D planar linear elastic problem



Here is the simple code for FEM. The features are following:

1. Linear elastic material

2. Both 4 node and 8 node isoparametric rectangular element is implemented

3. Accept displacement and force boundary condition.



Usage:

1. For new FEM learner to understand the implementation.

2. Two input file is given. Only data output is given. Users should find post-processor for themselves.

3. See the comment in the code for details.
