The interface of two low-density materials is bent in the forming process, which decreases the performance of materials.
The decay rates of frictional force of these two materials are △fa, △fb .

Micro-deformation mechanism of granular materials under different boundary conditions based on DEM simulation Zhaoxia TONG1,a ,Min ZHOU1,b and Yangping YAO1,c 1School of Transportation Science and Engineering, Beihang University, Beijing,China atongzx@buaa.edu.cn, blwmdelp@foxmail.com, cypyao@buaa.edu.cn Keywords: Boundary condition; Micromechanics; Discrete element method (DEM); Granular material; Abstract.
The micro-deformation mechanism of anisotropic granular materials under different boundary conditions was analyzed in detail.
Meanwhile, particle rotation plays a dominant role in the development of shear bands in granular materials.
The mechanical properties of granular materials were affected greatly by the long axis orientation of particles.

In this paper, we focus on the need for the study of interface characteristics between different reinforced materials and clay, by making indoor drawing test with two kinds of reinforced materials commonly used in engineering and the same clay.
With the rapid development of Reinforced earth technology, different reinforced materials are also gradually applied to reinforced earth, In this paper, we focus on the need for the study of interface characteristics between different reinforced materials and clay, by making a indoor drawing test with two kinds of reinforced materials commonly used in engineering and the same clay.
The two kinds of reinforced materials drawing test results is shown in table 3.
