A mathematical model for the interaction force of an edge dislocation in the substrate near a surfacelayer is developed. 本文提出了材料表面层与基体材料中刃型位错的交互作用模型。
The test showed that the result of bending strength using dislocation rate loading is identical to the result using stress rate leading. 试验表明，以选定的位移速率加荷与以应力速率加荷所得的抗折强度结果一致。
