求解非局部弹性场方程以确定弹性板中线裂纹附近的应力状态，该弹性板在裂纹尖端表面受到均匀剪切。基于最大剪切应力的断裂准则给出了裂纹变得不稳定的所施加剪切的临界值。计算脆性材料破坏原子键所需的内聚应力。
Field equations of nonlocal elasticity are solved to determine the state of stress in the neighborhood of a line crack in an elastic plate subject to a uniform shear at the surface of the crack tip. A fracture criterion based on the maximum shear stress gives the critical value of the applied shear for which the crack becomes unstable. Cohesive stress necessary to break the atomic bonds is calculated for brittle materials.
