这门课程将将微分方程的理论、数值逼近和相关的应用结合在一起讲述。

A warp skeleton method was proposed to solve the descriptive issue of arbit rary 3D woven composite architecture , with the unit cell being decomposed into subcells/ grids. The subcell vector concept was int roduced to digitalize the 3D architecture , in order to use the 2D database table to store it .

利用经纱脉络描述法解决了任意三维机织复合材料的结构表征问题；提出了单胞分解法与亚胞向量概念，实现了三维结构的二维化、数字化，根据数字表征结果和经典截面假设构造了初始断裂模型；使用一种迭代算法对初始断裂模型进行优化，使纱线束逐步逼近真实形态，进而实现三维实体造型，在此基础上进行网格剖分。
