The goal of
this project is to develop models that can describe the
nano-scale mechanisms of deformation at asperity
contacts between surfaces. These models provide
the basis for multi-scale models of friction and wear.
There are four projects:
1.
Experimental studies of deformation mechanisms in
self-assembled nanoscale pyramids on surfaces (J. Wang, Kim)
2. Molecular
dynamic and continuum simulations of deformation
mechanisms in self-assembled nanoscale pyramids on
surfaces D. Ward, W. Curtin, K.S. Kim, Y. Qi
3.
Measurements of residual stress induced by dislocation
nucleation at surface steps under contact loading P.
Shrotriya, J. Wang, K.S. Kim
4. Molecular
dynamic simulations of dislocation nucleation at surface
steps under contact loading P. Shrotriya, J. Wang, K.S.
