The proposed formulation has been applied to the case of a cantilever edge-cracked nanobeam, performing a parametric study to analyse the mechanical behaviour by varying the crack depth and the crack location along the beam axis. Finally, the formulation has been applied to some experimental data available in the literature. It has been observed that: (i) for the silicon materials analysed, a satisfactory agreement between experimental and analytical results has been obtained, being the numerical curves perfectly inside the experimental scatter bands; (ii) for the FeAl single crystalline material, a maximum error on the deflection equal to about -10.36% is obtained with respect to the average experimental one, when the load is equal to 960µN.
