To investigate the nanometric cutting mechanism and removal processes of materials, molecular dynamics method is utilized to conduct single crystal copper nanomachining processes simulation, and nanocutting mechanism and removal processes are analysised by revised centro-symmetry parameter method. The results show that the cutting force of (111) orientation workpiece are largest, and that of (110)...
Focusing on the special need of nano-engineering, an improved neighbor list algorithm for the ultra-large scale molecular dynamics (MD) simulation is proposed. The new algorithm is attempting to fully combine the advantages of both Verlet table and cell-linked list algorithms to accelerate the speed of neighbor list construction and update. In order to meet the requirement of nano-engineering that...
