采用初始应力法进行被动土压力分析，程序中对相关矩阵及每一步的意义进行了简要说明(The code uses the initial stress method to analyze the passive earth pressure. The relevant matrix and the significance of each step are briefly explained in the program.)

说明：  该程序可进行2D和3D恒定流分析，程序中对矩阵含义和比较难理解的部分进行了简要说明(The program can be used for 2 D and 3 D constant flow analysis. The meaning of matrix and the parts that are difficult to understand are briefly explained in the program)

说明：  三层框架，瑞雷阻尼。 激励是白噪声。 先计算得到理论的响应时程，理论频率，再利用响应做峰值法识别频率模态，与理论频率对比。 程序只写到了画ANPSD曲线，还需要自己写一个拾取峰值的代码。(Three story frame, Rayleigh damping. The excitation is white noise. First, the theoretical response time history and frequency are calculated, and then the peak response method is used to identify the frequency mode, which is compared with the theoretical frequency. Later, you need to write a code to pick up the frequency corresponding to the peak value.)

说明：  ABAQUS摩擦系数子程序，可以用于数值计算(ABAQUS friction coefficient subroutine)

abaqus的平板约束数值模拟源文件，适合abaqus新手操作练习使用(ABAQUS source files for numerical simulation of plate constraints, suitable for ABAQUS novice operation exercises)

说明：  Abaqus中用于用户自定材料属性的子程序编程实例，适用于初学者。(ABAQUS subroutine programming example for user defined material properties, suitable for beginners.)

说明：  铝合金门窗辅助设计营销。输入门窗洞口尺寸，系统自动打印下料单、玻璃单、示意图、收银……(Aluminum alloy doors and windows aided design marketing. Input the size of the door and window opening, the system automatically prints the blanking list, glass sheet, schematic diagram, cash register...)

abaqus的残余应力数值模拟源文件，适合abaqus新手操作练习使用(ABAQUS source files for numerical simulation of plate constraints, suitable for ABAQUS novice operation exercises)

针对轨道动力学，模拟轨道不平顺的matlab编程，对轨道增加不平顺性，美国六级谱(Addition of track irregularity)

说明：  黏弹性阻尼器试验设计，方案以及尺寸设计，涉及到相似转换原则(Test Design of Viscoelastic Damper)
