摘　　要：文章构建密质骨双裂纹反平面模型,通过复变方法求解了该模型问题,并给出了裂纹尖端处应力及应力强度因子的解析表达式。数值算例分析了骨单元与基质的剪切模量比、裂纹尖端处与骨单元中心的距离和裂纹长度对裂纹尖端应力强度因子的影响。In this paper, the model of the double plane crack of the dense bone is constructed, and the model problem is solved bythe complex method, stress at crack tip and the analytic expression of stress intensity factor is given. Numerical example analyzes theinfluences shear modulus ratio of bone unit to stroma, the distance between the crack tip and the center of bone unit center, and influencethe crack tip stress intensity factor on crack tip stress factor.
