本文对二维摩擦颗粒系统在定常压力作用下的振荡剪切进行了数值模拟。我们发现，该系统经历的应变增加的双折射。我们证实，压实也发生在一个中间的应变幅度为一个小的相互摩擦系数之间的颗粒。压实度与围压有关，而压实度与围压关系不大。
We perform numerical simulations of a two-dimensional frictional granular system under oscillatory shear confined by constant pressure. We found that the system undergoes dilatancy as the strain increases. We confirmed that compaction also takes place at an intermediate strain amplitude for a small mutual friction coefficient between particles. We also found that compaction depends on the confinement pressure while dilatancy little depends on the pressure.
