cohesive element模拟复合材料损伤-VUMAT

对实际采集的舰船辐射噪声进行了demo谱分析，分别采用了窄带解调和宽带解调两种方式，得到了较清晰的轴频和叶频信息。(use narrow-band and broad-band methods to demodulate the ship-radiated noise which is actually colleted, there can see clear axle frequency and blade frequency in the demo spectrum.)

本程序应用python编程，用到3机9节点算例，数据也给出，可以实现潮流计算。(This program uses python programming, uses 3 machines and 9 nodes to calculate the example, and the data is also given, which can realize the load flow calculation.)

分支界限费用矩阵的说明文档，非常实用,建议下载哦(Branch line cost matrix documentation, very practical, it is recommended to download Oh)

说明：  9跨每跨35米桥梁响应的车桥耦合程序，使用Fortran编写(9 of 35 meters span bridge across every bridge coupled response procedures, the use of Fortran written)

隐式高斯法求解三相不平衡配电网的潮流计算，很实用，欢迎下载。(Implicit Gaussian method for solving three-phase unbalanced load flow calculation of the distribution network, very practical, welcome to download.)

用于焊接模拟的fluent的双椭球体热源UDF程序。(For welding simulation fluent double ellipsoid heat source UDF program.)

采用最小二乘方法的高斯曲线拟合算法， 用C 语言编写. 包含子程序.(Gaussian Curving Fitting with C language)

说明：  简单地实现了一、二、三维的K均值聚类，效果还不错，适合初步学习模式识别的同志们(Simple implementation of one, two, three - dimensional k-means clustering, the effect is not bad, it is suitable for the initial learning pattern recognition comrades)

这是最小二乘法多项式拟合的算法 很有参考价值的程序,(This is the least squares polynomial fitting algorithm is very useful procedure,)

这个帖子中我想讨论的是移动窗口多项式最小二乘拟和平滑方法，粗糙惩罚方法，以及kernel平滑方法。(Posts in this discussion I think are moving window least squares polynomial fitting smoothing method, crude methods of punishment, as well as the kernel smoothing method.)
