集中力作用下含尖孔无限域的反平面剪切问题

ANTI-PLANE SHEAR OF AN INFINITE BODY CONTAINING HOLE WITH CUSPS APPLIED BY CONCENTRATED FORCES

论文采用了一种新的方法求解含尖孔无限域的反平面剪切问题，以闭合形式导出了在集中力作用下，孔口尖点的应力强度因子表达式．同时，给出了对称翼状尖孔、内摆线状尖孔、唇状尖孔及圆孔径向边裂纹的应力强度因子．其结果在理论上和应用中都具有重要的意义．

A new method is used to find the stress intensity factors at cusps of holes in a infinite body applied by concentrated forces.Some derailed discussion are on hypocycloid holes,symmetric airfoil cracks,symmetric lip cracks and equally spaced radial cracks extending from the edge of a circular hole.The resultes will be of theoritical and applied importance.
