计算孔口应力集中的计算复变函数方法。本人自己编的程序，可读性比较差。-Calculation of stress concentration calculation orifice complex variable function method. I own procedures, a relatively poor readability.

用matlab分析由n个单胞组成的桁架在受到最外节点处的集中力是的位移及应力应变，并对整个结构进行优化设计。-Matlab analysis by single cell formed by the n truss subjected to the most outside the nodes in the concentration of power is the displacement, stress and strain, and the entire structure is opti
