## What is/are Gradient Nanobeams?

Gradient Nanobeams - A parametric study has been performed to analyze the significance of considering the surface effect on the vibration behavior of nonlocal strain gradient nanobeams with varying values of nonlocal parameter, length scale parameter, gradient indices and slenderness ratio for three different boundary conditions.^{[1]}The forced vibration behaviors are examined for nonlocal strain gradient nanobeams with surface effects subjected to a moving harmonic load travelling with a constant velocity in terms of three beam models namely, the Euler-Bernoulli, Timoshenko and modified Timoshenko beam models.
