铰接薄壳的后屈曲分析

这是一个用于演化博弈 画图 code 的代码，里边有函数和计算过程，大家可以结合自己需要看看(evolutional game model code)

说明：  通过设置不同的参数，生成BA无标度网络。(This progarm is to create a BA network by setting different parameters.)

说明：  薄壁圆柱壳轴压屈曲非线性计算，采用模态缺陷作为初始缺陷(In the nonlinear calculation of thin-walled cylindrical shells under axial compression, modal defects are used as initial defects)

三相桥式全控整流电路仿真，使用晶闸管进行三相桥式全控整流电路仿真。(Three-Phase Full-Bridge Controlled Rectifier)

说明：  matlab画三维凸包，根据一些离散点，效果非常好(Matlab draws three-dimensional convex hull, according to some discrete points, the effect is very good.)

说明：  abaqus纯镁切削算例文件，可直接计算(ABAQUS pure magnesium cutting example file can be directly calculated)

说明：  常规波束形成与最小方差无畸变算法性能对比（CBF、MVDR）(Performance comparison between conventional beamforming and minimum variance distortionless algorithm CBF MVDR)

说明：  一受均匀拉力的板，中心带贯穿裂纹，裂纹长2a，使用4节点单元计算裂尖应力分布和应力强度因子(A uniform tensile plate with a through crack in the center and a crack length of 2a is used to calculate the stress distribution and stress intensity factor at the crack tip using a four node element)

说明：  Incoherent Scatter Radar model in Matlab. To calculate the theoretical spectra of radars.
