Abstract: The elastic deformations in the conical nanowires are considered. An analytical expression was obtained for the distribution of elastic deformations along the length of the conical nanowire. It was found that at certain cone angles in nanowire there is an extended area of sufficiently high deformations comparable or even large than the deformation at the base of the nanowire. So, for example, when bending the conical (conical coefficient $a$ = -0.7) nanowire with length $L$ = 1 $\mu$m and radius $R$ = 50 nm by $\Delta z$ = 200 nm, the maximum deformation values are $\varepsilon_{{xx},\mathrm{max}}$ = 8%, while more than 95% of the nanowire is deformed by $>$ 3%.

Keywords: nanowires, elastic deformations, conical nanowires, Young’s modulus.
