本文讨论了离散元法在颗粒摩擦中的应用及其有效的(或简化的)宏观模型。本文着重研究了剪切颗粒摩擦过程中的粘滑运动,这与Nasuno等人的实验相对应(Phys.Rev.E58(1998),2161)。我们再现了他们的许多实验结果的DEM模型和有效模型的模拟。
This paper discusses the application of the distinct element method (DEM) for granular friction and its effective (or simplified) macroscopic model. We focus on the stick-slip motion in a sheared granular friction process which corresponds to an experiment by Nasuno et al. (Phys. Rev. E 58 (1998), 2161). We reproduce many of their experimental results from the simulations of the DEM model and the effective model.
