From atoms to a tensile test This research
program is a fundamental investigation of the
mechanisms of deformation and failure in
nanocrystalline materials. We have carried out
virtual tensile tests in bulk digital samples of
nanocrystaline Ni. We have studied the response
of nanocrystaline Ni nanowires in tension, at
the atomic scale. The virtual tensile tests were
performed in Virginia Techs new supercomputer.

• Education
• The PI co-authored a chapter in the Handbook of
  Materials Modeling, edited by S. Yip and
  published by Kluwer, in 2004.
• J. Monk, graduate student worked on CAVE virtual
  reality visualization of our tensile tests for
  teaching purposes.
• Visualization tools were set up in our lab to be
  used by several groups working on computational
  materials science.

• Undergraduate student M. Willemann participated
  in the first atomistic simulation research of
  fatigue response of nanocrystalline materials
  (Phys. Rev. Lett. 94, 165502 , 2005)
