An Investigation of Nanoscale Tribological Characteristics for Different Geometrical Sliding Systems
The slider geometry has a great influence on tribological behaviors for nanoscale sliding systems. The present study employs the finite element method (FEM) atomic approach to investigate the friction behaviors for rectangular slider and triangular slider on slab. The current investigation chooses diamond-like carbon as the hard material, and copper as the soft material. The atomic configurations following sliding under non-interactive, attractive, and repulsive force field are observed for sliding system. The relationships between the normal force, the friction force, and the sliding distance are discussed. The present results are in good agreement with those of previous studies using molecular dynamics (MD) simulation.
