Title: Predictive Simulation and Design of Materials by Quasicontinuum and Accelerated Dynamics Methods

Technical Report ·
DOI:https://doi.org/10.2172/1126455· OSTI ID:1126455

This project developed the hyper-QC multiscale method to make possible the computation of previously inaccessible space and time scales for materials with thermally activated defects. The hyper-QC method combines the spatial coarse-graining feature of a finite temperature extension of the quasicontinuum (QC) method (aka “hot-QC”) with the accelerated dynamics feature of hyperdynamics. The hyper-QC method was developed, optimized, and tested from a rigorous mathematical foundation.
