abaqus 插件，在abaqus程序中生成随机位置的纤维,需要指定数量、纤维半径、长度。(This file is a plugin of abaqus . It is used to generate fibers of random positions. Fiber number,radius,length are needed to input at first.)

matlab生成随机分布纤维代码，用于后续模拟处理(Matlab generates randomly distributed fiber code for subsequent simulation processing)

生成三维随机纤维的matlba程序，可以直接使用(The matlba program for generating 3D random fibers can be used directly)
