Slow dynamics modeling of nano-scaled materials deformation

We developed modeling methods for nanoscale slow dynamics in materials and confirmed its availability by applying them to actual slow dynamics problems. We achieved the following six objectives.(1) Development of accelerated moleculardynamics modeling theory(2) Development of multi-replica molecular dynamics simulation code(3) Development of improved accelerated molecular dynamics method (adaptive boost method)(4) Understanding of deformation mechanism of nanocrystalline metals(5) Understanding of relation between local atomic structure and local mechanical properties in metallic glass systems(6) Modeling of dislocation -solute atom coupling dynamics.
