Nano structures such as nanowires, nanobeams and nanoplates have been
investigated widely for their innovative properties. In this paper the buckling
of nanowires surrounded in a Winkler - Pasternak elastic medium has been
examined based on the nonlocal Euler-Bernoully model with considering the
surface effects. In the following a parametric study that explores the influence
of numerous physical and geometrical parameters on the buckling of nanowires
is presented. It has been shown that by growing the ratio of surface area to
bulk in nano-size structures, the effect of surface energy turn out to be
important and should be taken into consideration. Moreover the results point
out that surface elasticity and residual surface tension stimulus the buckling
behavior of nanowires.
