论文摘要
我们对持续压力限制的振动剪切剪切剪切下的二维摩擦颗粒系统进行数值模拟。我们发现，随着应变的增加，系统会发生膨胀。我们证实，压实也发生在颗粒之间的小互动系数的中间应变振幅下。我们还发现，压实取决于限制压力，而膨胀很少取决于压力。
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.
