| الوصف: | The effects of tensile or compressive prestress on the torsional responses of carbon nanotubes are examined using classical molecular dynamics simulations. Prestressing the nanotubes is predicted to significantly change their critical torsional moment and stiffness. This is therefore an approach by which the torsional mechanical properties and oscillation frequencies of carbon nanotubes may be tuned. Importantly, the predicted changes in torsional stiffness are unique relative to conventional linear elastic materials and are indicative of nonlinear oscillations due to nonlinear mechanical effects. |
