说明：  umat基础知识教学，适合刚接触UMAT的新手做参考(UMAT basic knowledge teaching, suitable for beginners)

说明：  一个计算铜的热导率的in文件，基于lammps软件(An in file for calculating thermal conductivity of copper)

说明：  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)

说明：  fluent UDS的一段程序，可以照着这个自学UDS，很好用(A program of fluent UDS can be used for self-study according to this UDS)

说明：  这个程序是通过设置不同的参数来创建一个随机图，可以运行。(This program is to create a random graph for simulation.)

三个ANSYS瞬态分析的命令流：冲击载荷作用悬臂梁的阻尼振动分析；破碎锤的瞬态动力学分析；滑动摩擦接触分析(Three command streams of ANSYS transient analysis: damped vibration analysis of cantilever beam under impact load; transient dynamic analysis of crushing hammer; sliding friction contact analysis)

用于随机粗糙面建模的蒙特卡罗算法程序包含一维和二维算法(Monte Carlo algorithm for random rough surface modeling)

说明：  本模型采用abaqus自带的connector连接单元建模，实现了钉节点的模拟(In this model, the connector unit of ABAQUS is used to simulate the nail node)

说明：  这个是信号与处理专业的大作业，主要研究两个方面的问题：低通滤波器的阶跃响应特性分析和连续线性系统的求解。通过这次课程设计，将会研究Matlab的一些基本的数值计算应用方法，对计算结果进行形象化地展示，有利于加深对本课程内容的理解。(This is a major task of signal and processing specialty. It mainly studies two aspects: step response characteristic analysis of low-pass filter and solution of continuous linear system. Through this course design, we will study some basic numerical calculation application methods of MATLAB, and visualize the calculation results, which is conducive to deepening the understanding of the course content.)
