本文综述了致密颗粒介质的建模在过去15年中取得的进展。我们回顾的出发点是干颗粒流的μ(I)流变学，它打开了通用流场建模的大门，但主要是针对涉及简单形状的小单分散颗粒的问题。我们的综述主要集中在模拟更多材料类型和行为的进展，包括模拟有限粒度效应或非局域性、多分散性和非平凡颗粒形状的新方法。我们还讨论了可处理的订单减少策略的增长应用领域，重点是入侵和移动问题。
This review focuses on how the modeling of dense granular media has advanced over the last 15 years. The jumping-off point of our review is the μ( I) rheology for dry granular flow, which opened the door to generic flow field modeling but was primarily geared toward problems involving small monodisperse grains of simple shapes. Our review focuses on advances in modeling more material types and behaviors including new approaches for modeling finite-grain-size effects or nonlocality, polydispersity and unmixing, and nontrivial grain shapes. We also discuss growing application areas with tractable order-reduction strategies with a focus on intrusion and locomotion problems.
