用锁定加速度计研究侵入体对颗粒物质的侵彻
Intruder penetration into granular matter studied by Lock-in Accelerometry
摘要：
了解侵入体在颗粒层中的渗透动力学不仅与基础物理学有关，而且与可能受地震影响的地区的沉积物或颗粒土壤上的地球物理过程和建设有关。在这项工作中，我们使用Lock-in加速度计来研究入侵者对准二维颗粒物质的横向振动流化的渗透。我们观察到，有两个明确的阶段，在渗透动力学的入侵者沉入颗粒状材料。
英文摘要：
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental physics, but also for geophysical processes and construction on sediments or granular soils in areas potentially affected by earthquakes. In this work, we use Lock-in accelerometry to study the penetration of intruders into quasi-2D granular matter fluidized by lateral shaking. We observed that there are two well-defined stages in the penetration dynamics as the intruder sinks into the granular material.
