Peculiarities of Limiting States in Simulated Drained and Undrained Assemblies of Elliptical Particles

摘要：

　　The study is aimed at characterizing micromechanical characteristics of large shear strain behavior during transition to critical/steady state in simulated granular assemblies.It is demonstrated that there are substantial differences in which various attributes of micromechanical response evolve in drained and undrained situations,pointing to the possibility that volumetric constraints due to presence of fluid in voids may alter mechanisms of large strain behavior in comparison with drained response.
