Abstract In this paper, the densely arrayed bonded particle model is proposed for simulation of granular materials with discrete element method (DEM) considering particle crushing. This model can solve the problem of pore calculation
after the grains are crushed, and reduce the producing time of specimen. In this work, several one-dimensional
compressing simulations are carried out to investigate the effect of particle crushing on mechanical properties of
granular materials under a wide range of stress. The results show that the crushing process of granular materials
can be divided into four different stages according to er-logσy curves. At the end of the… More >
