Abstract

We present some numerical results for the linear dynamics of nanobeams modulated by an axial

force, basing on a recent proposal of literature that encompasses both the standard nonlocal elasticity,

according to Eringen, and second-order strain elasticity. Three different possibilities for the

elastic potential energy provide different responses that highlight the contributions of nonlocality

and strain gradient, plus their combination. An axial force affects the linear stationary dynamics

of such nanobeams, inducing suitable variation of the natural angular frequencies for benchmark

cases, until static buckling occurs when the natural angular frequency vanishes. Effects of the

various elastic potentials on this modulation are investigated and thoroughly commented.
