For most of granular materials, under external stress, it is very easy to cause grain breakage, which will have an obvious influence on the mechanical behaviour of materials.

大部分粒状材料在外力作用下较容易产生颗粒破碎，颗粒破碎对材料的力学性能有很大的影响。

The defect configuration relates directly to the mechanical behaviour of structural materials. Especially, dislocation substructure, DSS, is one of the most important configurations.

缺陷组态直接涉及到结构材料的力学性能，特别是位错亚结构(DSS)为最重要的缺陷组态中的第一个。
