Abstract

Nanoscale porosity appears in solids under a number of conditions: during the initial stages of ductile failure, due to radiation damage in nuclear reactors, due to fabrication or synthesis methods of certain materials, etc. Understanding the mechanical behavior of these materials is crucial to understand failure under a variety of situations, and to assess the applicability of structural materials under extreme conditions of deformation at high stress and strain rate. Experiments that probe the relevant nanoscopic length and time scales are extremely difficult or impossible with current set-ups, and continuum models might not work at the nanoscale. As a result, atomic-scale simulations can provide unique insights, possible links to models at the micro-scale, and help interpretation of experiments that average over the macroscale. We consider atomistic molecular dynamics (MD) simulations covering mainly two scenarios.
