不同位置裂纹间的互相作用及其影响规律的有限元分析
Interaction and Influence between Cracks in Different Positions through Finite Element Analysis
【摘要】 基于有限元软件France-2D,利用J积分对含有多个裂纹的板进行应力强度因子计算。通过定义基础裂纹、干扰裂纹以及干扰参数,给出了随干扰参数改变,干扰裂纹对基础裂纹应力强度因子的影响曲线,并分析了它们的规律,其结果可为工程应用参考。
【Abstract】 Base on the finite element software France-2D,the J integration is utilized to calculate the stress intensity factor for the plate with multi-cracks.Through the definition of basic crack,disturbing crack and disturbing parameters,the influences of disturbing cracks on the stress intensity factor of basic crack are presented with the change of disturbing parameters.The regulation is analyzed.The results can be used as reference for the application.
