This variability vanishes at large diameters. The zigzag nanotubes follow similar behavior with an averaged converged value of radial Youngs modulus equal to 1.252 TPa. The difference between radial Youngs modulus for both geometries is approximately 2% where Youngs modulus of armchair is slightly higher than the zigzag configuration.
Evaluation of Tensile Modulus of Carbon Nanotube Carbon nanotubes (CNTs) possess extremely high stiffness, strength, and resilience which can values of Transverse Youngs modulus remain 5.26 GPa for any CNT diameter. But the values which is obtained from simulation varies from "Evaluation of Tensile Modulus of Carbon
The effective modulus of the SWNTs has been found to be in the range 530700 GPa which, while being impressive, is lower than the generally accepted value of around 1000 GPa as a result of factors such as finite length effects and nanotube bundling.Evaluation of Youngs Modulus of Single Walled Carbon Evaluation of Young s Modulus of Single Walled Carbon Nanotube (SWNT) Reinforced Concrete Composite. Authors :Ghandi Rouainia and Kamel Djeghaba. Abstract:Carbon nanotubes have excellent mechanical properties that make them ideal reinforcing materials, lab Researches observed crack bridging, bonding and fiber pullout in CNT/cement composites, these results paved the way to
