Mechanical characterization of single-walled carbon nanotubes

Abstract

Carbon nanotubes (CNTs) are fetching curiosity among scientists and researchers because of their extraordinary mechanical, thermal and electrical properties such as high stiffness, high strength, resilience, and many more and having extensive potential applications in numerous sectors, such as aerospace, automobile, biomedical, defence, energy, etc. Single-walled nanotubes (SWNTs) are extensively used with reference to reinforcing elements in advanced composite structures with less weight because of their high value of Young’s modulus (1 TPa) if normalized to their diameter. The mechanical properties of SWNTs can be determined through experimental, numerical and computational methods. In the present work, Materials Studio software based on molecular dynamics theory has been used for the examination of the mechanical properties of SWNTs. The results have been obtained for different values of strains in reference to Young’s modulus and Poisson’s ratio. It has been concluded that the obtained mechanical properties are in fair agreement with the base paper. © 2024 selection and editorial matter, Saumya Shah, Hemant Nautiyal, Gaurav Gugliani, Ashwani Kumar, Tanuj Namboodri and Yogesh Kumar Singla; individual chapters, the contributors.
