A macro and micro mechanics model is presented based on the relation between macroscopic and microscopicstress and strain fields, in which composite macroscopic stress strain relation is obtained.
基于复合材料宏、细观场量之间的联系,建立了一种纤维增强复合材料宏—细观力学模型。

Constant flexing of the structure concentrates stress, which leads to microscopic cracks.
这些构造部位的频繁伸缩使应力集中,导致微裂纹的产生。

Then, combining with microscopic observation of rock specimen sections under compressive loads, the phenomena of stress crack and the dynamic branch have been analysed and discussed.
