摘要：
本文研究了由摩擦颗粒组成的三维颗粒系统中解阻转变的过程，通过随机移除颗粒系统地降低颗粒浓度。利用离散元方法（DEM）模拟，分析颗粒间力、协调数和整体堆积密度随颗粒间摩擦系数的变化。结果揭示了摩擦系数对结构和机械特性的依赖关系，趋势与致密颗粒系统观察一致。这些趋势在考虑的非常不同的驱动机制下仍然保持。本文是主题问题“沙子、料仓和小行星：颗粒材料研究中的聚集体挑战”的一部分。
英文摘要：
In this work, we investigate the unjamming transition in a three-dimensional granular system composed of frictional spheres, in which the packing fraction is systematically reduced by random particle extractions. Using Discrete Element Method (DEM) simulations, we analyze the evolution of key micro-mechanical quantities, such as the interparticle forces, the coordination number and the overall packing density as a function of the interparticle friction coefficient. Our results reveal friction-dependent relationships on structural as well as mechanical observables, and exhibit trends that are qualitatively consistent with observations reported in dense granular systems. These trends persist despite the very different driving mechanism considered here. This paper is part of the thematic issue \emph{``Sand, silos and asteroids: clustering challenges in granular materials research''}.
