The theoretical strength of diamond-like nanoparticles under uniaxial stretching and compression is calculated by the method of pseudopotential. The surface energy of a nanoparticle is defined through the energy of interaction of atomic planes. The functional dependence of the strength on the size, depression, and form of a nanoparticle (nanoplate, nanobar) is obtained. The minimum distance from the external surface of a nanobar, where the theoretical strength
coincides with its value for massive samples, as well as the minimum area of the nanobar base when the theoretical strength does not depend on the base form, is evaluated.
