One of the recent advances in materials science has focused on developing materials that have two or more crystalline systems mixed at the nanoscale. Until now, the development and the analyses of such materials have primarily been experimental. In the current research, a framework based on classical molecular dynamics (MD) is developed for analyzing deformation mechanisms in nanostructural materials consisting of more than one crystalline system.

One of the recent advances in materials science has
focused on developing materials that have two or
more crystalline systems mixed at the nanoscale.
Until now, the development and the analyses of such
materials have primarily been experimental.
In the current research, a framework based on
classical molecular dynamics (MD) is developed for
analyzing deformation mechanisms in nanostructural
materials consisting of more than one crystalline
system. The material system of focus is a
combination of fcc-Al and -Fe2O3. The framework
includes the development of an interatomic
potential, a scalable parallel MD code,
nanocrystalline composite structures, and
methodologies for the quasistatic and dynamic
strength analyses. The framework is applied to
analyze the nanoscale mechanical behavior of the
Al+Fe2O3 material system in two different settings.
First, quasistatic strength analyses of
nanocrystalline composites with average grain sizes
varying from 3.9 nm to 7.2 nm are performed. Second,
shock wave propagation analyses in single
crystalline Al, Fe2O3, and one of their interfaces
are carried out.
