Atomistic Simulation of Cooperative Grain Boundary Sliding in Two-Dimensional Polycrystal
2012
Journal of Solid Mechanics and Materials Engineering
Preserved Fulltext
By means of molecular dynamics simulations cooperative grain boundary sliding is investigated during plastic deformation of two-dimensional nanopolycrystal at given temperatures and hydrostatic pressure. The mechanisms of obstacle overcoming are studied. It is demonstrated that the flattering of grain boundaries is the result of cooperative processes of grain boundary migration and dislocation sliding.
