Research Project Details
Project Duration: 
12/2011 to 12/2012
Project Significance: 
develop a multi-scale simulation scheme and design tool for modeling the mechanical and diffusion behavior of laminated structures consisting of materials with a variation of grain size ranging from nanometer to micrometers. The project is supported by Research Grants Council of the Hong Kong Special Administrative Region, China (Project no. CityU8/CRF/08).
Results Achieved: 
A comprehensive multi-scale theoretical model for predicting the mechanical behavior of the proposed periodic, multi-mode structure will be developed.
Remarks: 
All simulations are performed using the MD code, LAMMPS, developed by Sandia National Laboratory. Lammps a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator,Which can run in parallel using message-passing techniques and a spatial-decomposition of the simulation domain.
