| 摘 要： | Discrete Element Method(DEM) is used to study the flow pattern of loose powder which is indented by a rigid punch in an open die.Information such as trajectories or velocity of the particles movement and density distribution of the granular material during compaction is obtained.Typical powder flow characters in given areas can be observed in the theoretical simulation and experiment.It demonstrates that DEM can capture the major features of the powder flow behavior under low-pressure compaction when there is intense shear,and the conclusion of the flow behavior of compacted powder is useful to the industrial designing.
