Abstract
For the first time, this work employs analytic solutions to study static bending, as well as free and forced vibrations of organic nanobeams, including the impact of temperature. Calculation formulas are developed on the basis of the third-order shear strain theory of thickness. These formulas also account for the influence of the size effect by using nonlocal parameters. In contrast to the findings of earlier research on nanobeams, the nonlocal parameter in this investigation fluctuates with beam thickness. In addition to this, the viscous drag parameter of the beam is taken into consideration, which further complicates the calculation method, but this is also the new point of this work. The equation is developed using the potential work principle, and the Navier form solution is used to solve the resulting equilibrium equations. Nanobeams' natural frequency and static displacement have both real and complicated components due to the involvement of the drag parameter. The research also includes some numerical calculation findings for elucidating the impact of temperature and nonlocal parameters on the static bending response and free and forced vibration of organic nanobeams.
期刊介绍:
Archive of Applied Mechanics serves as a platform to communicate original research of scholarly value in all branches of theoretical and applied mechanics, i.e., in solid and fluid mechanics, dynamics and vibrations. It focuses on continuum mechanics in general, structural mechanics, biomechanics, micro- and nano-mechanics as well as hydrodynamics. In particular, the following topics are emphasised: thermodynamics of materials, material modeling, multi-physics, mechanical properties of materials, homogenisation, phase transitions, fracture and damage mechanics, vibration, wave propagation experimental mechanics as well as machine learning techniques in the context of applied mechanics.
