假设当两个接触面处于相对滑动的临界状态时，切向力与垂向力成正比。
Provided two contact bodies are in the critical state of relative sliding, the tangential force is proportional to the vertical force.
运用这种处理方法，可以近似反映接触面处的位移状态并模拟结构中实际存在的滑动面。
By employing the treatment, the displacement state at the interface is considered and the actual sliding area existing in the structure is simulated approximately.
