The quasi-static equations are obtained separately governing the stress and strain fields at the crack-tip by means of Airy's stress function. 引入Airy应力函数,求出了裂纹尖端应力和应变场的控制方程。
Author presents stress component's expression under polar coordinate while a single force is applied to horizontal rock formation by means of Airy's stress function. 通过极坐标系下的艾里应力函数法,求解出在集中力作用下水平岩层中各应力分量。
Both the stress and the displacement can be expressed by the mixed function, so the limitation that displacement can not be expressed in terms of Airy's stress function is overcome. 用该函数可以同时表示出应力和位移分量,克服了用Airy应力函数不易表示位移分量的缺点。
