摘要：
The discrete element method is used to simulate specimens under three different loading conditions (conventional triaxial compression, plane strain, and direct shear) with different initial conditions to explore the underlying mechanics of the specimen deformation from a microscale perspective. Deformations of specimens with different initial void ratios at different confining stresses under different loading conditions are studied. Results show that the discrete element models successfully capture the specimen deformation and the strain localization. Particle behaviors including particle rotation and displacement and the mesoscale void ratio distributions are used to explain the strain localization and specimen deformation. It is found that the loading condition is one of the most important factors controlling the specimen deformation mode. Microscale behavior of the granular soil is the driving mechanics of the macroscale deformation of the granular assembly. © Copyright.
