Free Vibration Of Bernoulli-Euler Nano-Beam Under Axial Load Using Nonlocal Strain-Driven And Stress-Driven Model

In this article, eigenfrequencies of nano-beam under axial load are calculated by strain-driven and stress-driven nonlocal model and Bernoulli-Euler kinematics. Used methodology is applicable to a wide variety of nano-engineered materials, such as carbon nanotubes. Eigenfrequencies, calculated with strain-driven and stress-driven nonlocal model, are compared with classical local theory and conclusions are given. The influence of nonlocal effects and initial axial force (tension and compression) on eigenfrequencies are analysed and results are documented. Model hardening and softening size effects are noticed and analysed.
