ABAQUS计算多相材料的前处理器 voronoi

说明：  复合材料层内基于断裂韧性退化的VUMAT子程序(VUMAT subroutine based on fracture toughness degradation in composite laminates)

数字信号处理FFT算法rfft.c，简单易懂。。(Digital signal processing FFT algorithm rfft,Straightforward..)

fft谐波分析的实例，并求出THD即谐波畸变率 (Examples fft harmonic analysis, and find THD)

说明：  借助python3计算偏微分方程组，并作出相应图形，代码简单易懂，方便修改(Calculate partial differential equations)

BESO的python程序，对于进行abaqus的二次开发很有帮助，这样可以将有限元单独在abaqus中进行处理，而优化算法则采用python进行编写(BESO python program, for the secondary development abaqus helpful, so that the finite element can be handled separately in abaqus, while the optimization algorithm is written in python)

Dot Matrix 5 x 7 sample progmam , hope you enjoy

润滑理论的matlab求解程序,包括弹流和刚流润滑.(Lubrication theory matlab solving procedures, including Elastohydrodynamic lubrication and just.)

说明：  基于OpenSEES平台的一个桥墩算例，可以供大家参考(An example of Bridge Pier Based on OPENSEES platform can be used for reference)
