Abstract (Summary)

Carbon nanotube has attracted researchers' attention due to their outstanding mechanical, electrical, thermal, chemical and even biological properties. However, due to the physical nature of CNTs, conducting experimental studies have been a challenging task among researchers and it is nearly impossible to obtain its engineering properties through conventional testing procedure.

Finite Element Analysis is utilized as a tool for conducting numerical simulations using Abaqus 6.10 CAE. We use Finite Element models of CNT and CNT reinforced composite, subjected to axial deformation along the length of the model, to investigate its behavior under various conditions and ultimately obtain its engineering moduli.

Multi-Scale modeling method is introduced, which calculates material properties/system behavior of one scale using information obtained from different scale, to obtain material properties of C-C bond element and non-linear spring element between C and CH2 molecules. We, then, construct CNT models and CNT reinforced composite models using Molecular Structural Mechanics and material properties obtained through Multi- Scale modeling method and its engineering properties are investigated.
