摘要
本文研究了两种材料的半空间组成的弹性体在交界面上含半无限平面裂纹时的裂纹尖端应力场与应力强度因子,应用弹性力学位移场的通解以及Kontorovitch-Lebedev积分变换求解出了在裂纹面上作用有对称法向载荷时的裂纹尖端应力场以及应力强度因子的具体形式。
In the paper, the stress singularhy and stress intensity factors of bimaterial clastic body with a semi-infinite plane crack in the interface of two materials are considered. Using the general solutions of displacement field in elasticity and the kontorovitch-lebedev integral transformation, we have obtained the exact forms of the stress sigularhy and intensity factors at the crack tip when a pair of symmetric normal concentrated forces are applied on the surface of the crack.
