冰的黏附和剪切变形传统上被认为是冰在低于约10−2 m/s的滑动速度下的摩擦的原因，但简单的机制不能解释最近的发现，即冰与冰的摩擦系数随着滑动速度的降低而增加。本文提出了一种改进的粘着剪切理论，该理论考虑了在滑动冰界面上由于烧结而导致的凹凸不平的结生长。在较低的滑动速度和较高的温度条件下，冰体之间的接触会增加摩擦力。
Adhesion and shear deformation of ice have been traditionally considered to be responsible for ice friction at sliding velocities lower than about 10−2 m/s, but the simple mechanism cannot explain the recent finding that the ice–ice friction coefficient increases with decreasing sliding velocity. This article proposes an improved adhesion shear theory, which takes account of junction growth of asperities at the sliding ice interface due to sintering. At lower sliding velocities and higher homologous temperatures, contacts of ice asperities develop resulting in the increase of friction force.
