这个解包括：裂纹线附近弹塑性边界上的单位法向矢量，裂纹线附近的弹塑性解析解、最大塑性区长度、裂纹线上的塑性区长度随荷载的变化规律及其承载力。

• The solutions include: the unit normal vector of the elastic-plastic boundary near the crack line, the elastic-plastic stress fields near crack line, law that the length of the plastic zone along the crack line is varied with an external loads, the maximum lengths of the plastic zone, the bearing capacity of a finite plate with an eccentric crack loaded by shear forces.
