Inelastic Continuum Modeling of Carbon Nanotube,s Behavior Using Finite Element Method

This paper describes a continuum model for analyzing the inelastic behavior of a single walled carbon nanotube (SWCNT) in different loading conditions. Because of limitations in using molecular dynamics (and other atomic methods) to model the failure load of the SWCNT, continuum mechanics methods are considered in this paper. Based on some experimental and theoretical results, an elasto-plastic...

Finite Element Modeling of the Vibrational Behavior of Single-Walled Silicon Carbide Nanotube/Polymer Nanocomposites

The multi-scale finite element method is used to study the vibrational characteristics of polymer matrix reinforced by single-walled silicon carbide nanotubes. For this purpose, the nanoscale finite element method is employed to simulate the nanotubes at the nanoscale. While, the polymer is considered as a continuum at the larger scale. The polymer nanotube interphase is simulated by spring ele...

Axial Crushing Analysis of Sandwich Thin-walled Tubes using Experimental and Finite Element Simulation

Application of impact energy absorption systems in different industries is of special significance. Thin-walled tubes, due to their lightness, high energy absorption capacity, long crushing length and the high ratio of energy absorption to weight, have found ever-increasing application as one of the most effective energy absorption systems. In this research, through  carrying out experimental t...

calculation of elastic modulus of reinforced nanocomposites by carbon nanotubes using finite element method, averaging approach and micromechanics relations

carbon nanotube (cnt), due to extraordinary mechanical properties, is an effective stiffener as reinforcement in resin for fabricating of nanocomposites. it is demonstrated by adding a small amount of cnt to the matrix, the elastic modulus of matrix increases remarkably. in this paper, the elastic modulus of cnt reinforced nanocomposites is obtained two-dimensionally using a finite element meth...

Single - Walled 4 . Single - Walled Carbon Nanotubes

Single-walled carbon nanotubes (SWCNTs) are hollow, long cylinders with extremely large aspect ratios, made of one atomic sheet of carbon atoms in a honeycomb lattice. They possess extraordinary thermal, mechanical, and electrical properties and are considered as one of the most promising nanomaterials for applications and basic research. This chapter describes the structural, electronic, vibra...
