In the framework of the theory of non‐local elasticity, a model on the buckling of a weakened nanobeam subjected to constant axial load is presented. Based on this model, the characteristic equation for a simply supported weakened nanobeam is obtained, through which the value of buckling load can be determined. The influences of small length scale and weakened junction on the buckling load are discussed. It is shown that the buckling load is dependent upon the scale coefficient, junction stiffness and junction location.
