The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。
