Abstract

In this computational lab you will perform online molecular dynamics (MD) simulations of nanoscale cracks under uniaxial tension through nanoHUB. Simulations with varying temperature and crystal structure will provide information to:

  • Distinguish the atomistic mechanisms of ductile and brittle failure and the relationship with temperature
  • Examine changes in crack propagation with crack length
