摘    要:
本文研究了颗粒材料的剪切变形机制,建立了颗粒体在变形过程中应力与组构量的相互关系,论证了产生剪胀的微观组构条件,推导出各向异性组构颗粒体剪胀方程。做了相应的单剪试验,理论结果与试验结果相当吻合,从而验证了理论模型的正确性。

关 键 词:颗粒材料 剪胀模型 微观组构

Abstract:
The mechanism of shear deformations for granular materials is studied by consi- deration of the fabric change,and then the stress-dilatancy equation is established. The shear dilating condition represented by microfabric factors is given.To verify the established model,the simple shear tests are performed.It is shown that the results of the experiments are fairly agreement with the theoretical results.
Keywords:granular materials  shear dilating model  microfabric
