A study on the friction and wear behavior in atomic scale by using MD simulation

Molecular dynamics simulation has been used widely to investigate the friction and wear behavior in atomic scale. In MD simulation, each atom which compose the material is assumed to be particle and to move in Newton's equation of motion. In our laboratory, friction and wear behavior is investigated by using MD simulation. Friction force, normal force, and friction coefficient are calculated as sliding speed and sliding depth. Morse potential is used to describe the interatomic force between copper and carbon atoms. In our laboratory, friction and wear behavior is investigated by using MD simulation.
