Abstract

Adhesive contact with the effect of tangential force may have important implications in friction and wear performances of small-sized devices and joining technologies. In the present work, adhesive contact involving tangential loading but before gross slip between spherical objects has been simulated through molecular dynamics (MD) to reveal the interaction between adhesion and the applied forces. When only the normal force is present, the results on force–displacement relationship and interfacial traction have been presented to compare with the predictions of Johnson–Kendall–Roberts (JKR), Maugis–Dugdale (M–D) and the Double–Hertz (D–H) models with the purpose of evaluating their applicability. In the presence of additional tangential forces, their interaction with adhesion has been studied in depth through loading and unloading. Distribution of the shear traction at the interface which is different from that in the existent models has been obtained. Those altogether may help to develop reasonable continuum models for adhesive contact under inclined forces.

切向力影响下的粘合接触分子动力学研究
切向力作用下的粘合接触可能会对小型设备和连接技术的摩擦和磨损性能产生重要影响。在本研究中,我们通过分子动力学(MD)模拟了球形物体之间涉及切向加载但尚未发生严重滑移的粘合接触,以揭示粘合力与外加力之间的相互作用。在只存在法向力的情况下,模拟结果与约翰逊-肯德尔-罗伯茨(JKR)、毛吉斯-杜格代尔(M-D)和双赫兹(D-H)模型的预测结果进行了比较,以评估它们的适用性。在存在额外切向力的情况下,通过加载和卸载深入研究了它们与附着力的相互作用。结果发现,界面上剪切牵引力的分布与现有模型不同。这些结果有助于为倾斜力作用下的粘附接触建立合理的连续模型。
