说明：  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)

梯形断面明槽水面曲线计算源程序,输入数据即可自动计算结果(Calculation of Water Surface Curve of Trapezoidal Section Open Channel)

说明：  徐世良经典算法集合，包含常用的各种算法，供大家下载参考(index for FEM code)

说明：  使用有限元方法，可以直接求解加筋板结构的质量刚度矩阵(Using the finite element method, the mass stiffness matrix of stiffened plate structure can be solved directly)

说明：  利用地震波生成加速度、速度、位移反应谱曲线(Using seismic wave to generate response spectrum curve)

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：  用于房屋、大坝、桥梁、水电站等大型结构的时程分析，根据桥梁抗震细则规范标准谱得到的25条地震波(For time history analysis of large structures such as buildings, dams, bridges and Hydropower stations, 25 seismic waves are obtained according to the standard spectrum of seismic rules for bridges.)

说明：  3维米塞斯屈服准则模型，子程序为vumat，用于abaqus(ABAQUS 3-dimensional Mises yield criterion)
