Abstract
This study presented a computational technique to model and simulate atomistic behavior of materials under static loads. Interatomic potential energy was used to maintain equilibrium among atoms under static loads and constraints. In addition, the atomistic model was coupled with the finite element analysis model so that more flexible loads and constraints could be applied to the atomistic model. A multi-scale technique was also presented for some single wall nanotubes of both zigzag and armchair and then their effective stiffness were estimated. Those designed nanotubes are woven into fabric composites, which can be used in various military applications including body armors, armored vehicles, and infantry transportation vehicles because advanced nano-composites could be much lighter and stronger than current ones. Some example problems were presented to illustrate the developed technique for the nano-composites and SWNTs. The proposed technique for nanomechanics can be used for design and analysis of materials at the atomic or molecular level.
