Abstract

In this computational lab you will learn about dislocations via online molecular dynamics (MD) simulations using nanoHUB. The simulations involve various types of dislocations in FCC and BCC crystals. During the learning module you will be able to:

  • Distinguish edge and screw dislocations in FCC and BCC crystals
  • Understand the propagation of both pure dislocation types, including Burger’s vector, line direction, and slip plane
