摘要
应力强度因子是断裂力学中表征裂纹尖端应力奇性场的强度的参量,其确定方法很多。通过应用ANSYS软件中的"位移外推"法对应力强度因子进行了计算分析,并与公式法计算出的理论值进行比较。结果表明:在误差允许的范围内,用位移外推法计算应力强度因子是可靠的。
In tracture mechanics,stress intensity factor（SIF） is a parameter about strength of singular field in crack tip stress, many ways can calculate it. In this study, a method of displacement extrapolation was adopted in calculating and analyzing on SIF. Comparaed with the theoretical calculation, it was turn out to an efficient way in calculation of SIF within error limit.
