ELM分类预测

光纤存在非线性效应，SPM、XPM、FWM，本算法为啁啾高斯光束在光线中传播的波形变化，采用了分步傅里叶法(simulation of fiber nonlinearity)

说明：  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)

三维比例导引法仿真，可以攻击静止/机动目标(Three dimensional proportional navigation simulation can attack stationary / maneuvering targets)

说明：  3.5 GHz 是 5G 网络部署的重要频段，本文结合射线跟踪模型，对 3.5 GHz 的无线传播特性进行了研究，并于 1.8 GHz 进行了对比，提出 5G 网络初期部署的建议(3.5GHz is an important frequency band for 5g network deployment. In this paper, the radio propagation characteristics of 3.5GHz are studied in combination with ray tracing model, and compared with 1.8GHz. Suggestions for initial deployment of 5g network are proposed)

说明：  用Fortran语言编写的abaqus，Dflux热源子程序，路径为环形路径(Abaqus, Dflux heat source subroutine written in Fortran language, with a circular path)

These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.

abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)

基于bpa的IEEE39节点算例，包含暂态数据和稳态数据(Example of IEEE39 node based on BPA)

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)

matlab连接安捷伦示波器，可以显示单个通道数据，自己设置采样点数，设置内存深度，可以通过改变循环达到长时间监控目的（数据传输有延时，用于捕捉信号时要延长监控时间）。(matlab Connect the agilent oscilloscope)
