A 3D Multiscale Simulation of Rough Surface Contacts at the Atomic Level

Investigating rough surface contacts at the atomic level is instrumental to the overarching understanding of tribology across the scales. Limitations of traditional techniques, such as purely atomistic and continuum simulations, motivate the development of multiscale simulations accounting for nanoscale contact. In this work, multiscale models are developed, and applied to investigate rough surface contacts at the atomic level with consideration of elastic deformation, elasto-plastic deformation, effects of temperature and lubricant.
