标题： Monte Carlo and MD Modeling of Density Relaxation by Tapping

摘要： 密度松弛现象通过蒙特卡罗和耗散分子动力学模拟进行建模，以研究对装有单分散球体的平面底部容器施加的常规敲击的影响。 结果表明存在一个临界敲击强度，该强度取决于覆盖层质量，会产生最大的整体固体分数。 我们发现导致松弛现象的机制是自平面底部向上传播的准有序包装结构。 显示英文摘要

摘要： The density relaxation phenomenon is modeled using both Monte Carlo and dissipative MD simulations to investigate the effects of regular taps applied to a vessel having a planar floor filled with monodisperse spheres. Results suggest the existence of a critical tap intensity that depends on the mass overburden, which produces a maximum bulk solids fraction. We find that the mechanism responsible for the relaxation phenomenon is evolving quasi-ordered packing structure propagating upwards from the plane floor.
