摘要：
Utilizing multiscale method, nanoscale sliding contacts problems are investigated in this paper. Several rigid multi-asperity tips are used to slide on an elastic substrate with different textured surfaces. Two elastic surfaces with different textures are considered, and the multi-asperity tips consist of several cylindrical asperities whose radii are different. Average friction forces and average normal forces are compared to show the effects of indentation depth, and the mechanism which results in high friction forces is also discussed. Finally, a better shape, which can help to reduce friction forces between surfaces, is suggested.
