报告内容简介：
This work uses nonlocal elasticity theory to demonstrate wave propagation in a thermoelastic single walled carbon nanotube. In the absence of a body, the Euler-Bernoulli beam model is used to develop the mathematical model of the issue that results in the governing equations. We arrive at the governing partial differential equation of motion using Eringen's nonlocal theory. The nonlocal interactions simulate the nanotube's small-scale interactions. Eringen's nonlocal elasticity theory, as opposed to traditional continuous models, is therefore a better instrument for researching the impacts of small-scale activities. Using nonlinear foundations, the Winkler-Pasternak model, and polymer spring constant constants, the frequency equations were numerically analysed. The critical buckling load calculated in my research is then compared to the recommended mathematical modelling for the entire research work. The dispersion curves are visually represented in each publication, and each graph of a physical variable is the subject of a discussion. Finally, utilising the available data, the numerical computations of system characteristics like dispersion have been tabulated and confirmed. The results of this study can be used to create mechanisms for the investigation and design of nanodevices, such as parts for nano oscillators, microwave absorbers, nanoelectronics, and nano-thermo-electro-magneto-mechanical systems (NTEMMS) that take advantage of the wave propagation characteristics of single-walled carbon nanotubes. There has been a reliable agreement achieved.
