In this study, models are proposed to analyze the combined effect of surface microgeometry and adhesion on the load–distance dependence and energy dissipation in an approach–separation cycle, as well as on the formation and rupture of adhesive bridges during friction. The models are based on the Maugis–Dugdale approximation in normal and frictional (sliding and rolling) contacts of elastic bodies...
The adhesive contact problem is stated and solved for two axisymmetric elastic asperities of different shape. The energy dissipation in an approach-separation cycle is calculated and analyzed. A model is suggested to determine the adhesive component of the sliding friction force based on calculating the energy dissipation in formation and breaking of contacts between asperities in sliding of rough...
