我们提出了一个简单的唯象模型来描述平板在匀速推进的颗粒层上的运动。该模型包含表征从类固体到类液体的转变的序参数。该模型再现了实验中观察到的摩擦力滞后现象和滑移速度的普遍分布。我们的模型预测磁滞回线的面积取决于推进速度。
We propose a simple phenomenological model to describe the motion of a plate on granular layers pushed at a constant speed. The model contains the order parameter characterizing the transition from a solidlike state to a liquidlike state. The model reproduces the hysteresis in frictional force and the universal profile of the slip velocity, which are observed in experiment. Our model predicts that the area of hysteresis loop depends on the pushing speed.
