    Abstract: The buckling behavior of a nonuniform nanowire
    under axial compression is studied using the nonlocal elasticity theory. We obtain an analytical expression for calculating the
    critical buckling load of the nanowire. The expression can be simplified for the special case of the nanowire with uniform cross section. Based on the simplified equation, the analyzed result agrees with the previous work. In addition, the influences of nanolocal and surface effects on the critical buckling load of the nonuniform nanowire are analyzed by using the Rayleigh-Ritz method. According to the analyzed result, it can
    be found that the critical buckling load decreases with an increase of nonlocal parameter. Furthermore, the surface
    effects are more significant for a slender nanowire with a higher diameter ratio.
