摘要
提出了一种数值方法来确定多重应力奇异性对应的应力强度因子,给出了求解多重应力奇异性的应力强度因子的另外一种捷径.特例表明它的精度符合工程应用的要求,并且对于所给的模型结构不需要划分过密的网格就可以得到令人满意的精度,为工程材料强度的评价提供了有效的计算工具.
A numerical method using finite element method (FEM) is given to define multi-singularity stress intensity factors (SIF), which is proved to be another efficient way in settling this problem. Its precision satisfies the requirements of projects after being testified by special examples. Moreover, the method can reach good precision without dividing intense nets, whose regularity and efficiency paves the way for calculating the multi-singularity SIF.
