摘　　要：在正交异性双材料界面裂纹的理论解的基础上,进一步探讨分析了正交异性双材料界面裂纹尖端应力强度因子的振荡奇异性;并通过实例讨论了双材料弹性常数对应力强度因子奇异性的影响。这个结论对今后相关课题的研究提供了新思路,具有较好的参考价值。Based upon the theory result of orthotropic bimaterial interfacial crack , the analysis of oscillatory of stress intensity factor at the interfacial crack tip of orthotropic bimaterial was done. And bielastic constant＇s effect on the stress intensity factor is discussed through examples. This conclusion has important value, it provides new idea for studying correlative problem in the future.
