摘要
开发了一个有限元软件 ,能对含有多个裂纹的构件进行断裂力学的 J积分计算 ,可对其中一个危险裂纹定义为基础裂纹 ,其他定义为干扰裂纹。给出了不同方向和位置的干扰裂纹对基础裂纹 J积分计算的影响 ,其结果可为工程应用参考。
A program of FEA has been developed to calculate the J integration for structures with multi cracks One among the cracks is taken as the basic crack and the other cracks regarded as disturbing cracks Influence of disturbing cracks located in various parts in relation to the basic crack is discussed in this article The result is believed to be of reference value to engineering applications
