Most mechanical properties of solid materials are driven by dislocations and dislocation interactions. Classical molecular dynamics (MD) simulations are uniquely suited for studying dislocation interactions as the simulations provide the necessary atomic level description of the defects involved, along with the capability of observing dynamic behaviors at finite temperatures. Obtaining useful results for these nanoscale mechanics from MD relies on developing robust simulation methods and understanding the associated model limitations. Here, a number of different simulation techniques are explored for investigating the interaction between vacancies/interstitials and dislocations in bcc metals. Results from the simulations reveal how the presence of these point defects influences the structure and motion of the dislocations.
