In nanoscale sliding systems, the cohesive energy has a fundamental influence on the tribological behavior. The present study employs a finite element method (FEM) approach to investigate the friction behavior of three slider/slab systems (soft-to-soft, hard-to-soft, and hard-to-hard) under different force fields and cohesive energies. The results indicate that the fluctuations of the normal and friction forces generated during sliding are more significant at higher values of cohesive energy in each of the three sliding systems. Furthermore, it is found that an increased cohesive energy causes more severe fracturing and adhesion phenomena in the sliding system.
