基于MATLAB的有限元分析 四节点平面的应力位移分析(Stress and displacement analysis of four node plane based on MATLAB finite element analysis)

该matlab程序为平面桁架的有限元分析程序，输入节点，单元，载荷信息就可以得到节点位移，节点荷载以及单元位移，内力，应力等结果。对刚度矩阵采用的方法是对角元乘大数法。程序注释文字清楚，准确。(The matlab program is a finite element analysis program for plane truss. The input node, element and load information can be used to get the results of n

平面8节点单元类，可以输出单元的刚度，并可通过形函数插值得到内部各点得位移、应力等。对各位以前编写的程序的一个补充和完善吧。(plane eight-unit category, the output unit stiffness, through the shape function can be interpolation points in the internal displacement and stress. Right before you and the procedure fo
