用光弹冻结应力法及解析法对具有斜裂纹的旋转园盘混合型应力强度因子进行了研究。当使用光弹条纹计算SIF时,文中给出最佳测取数据区域,可以提高确定应力强度因子的精度。结果表明解析法计算值与光弹性实验值是很接近的。
The mixed type stress intensity factor of rotating disk with oblique crack was studied by photoelastic freezing stress method and analytical method. When SIF is calculated using striae stripes, the best test data area is given in this paper to improve the accuracy of the stress intensity factor determination. The results show that the analytical value and the photoelasticity of the experimental values are very close.
