A continuum model of nanocrystalline metals under shock loading

Abstract:

Nanocrystalline metals, i.e., polycrystalline metals with grain sizes in the nanometer range, have recently elicited significant interest due to their potential for achieving higher material strength, especially under shock loading, reaching strength as much twice the value under normal conditions. The main source of deformation, grain-boundary sliding, has been found to be coupled to friction-like mechanisms decreasing the proportion of sliding resistance by an amount proportional to the app...
