The paper presents the comparison of the energy absorption by perfect and amorphized nanorods under the cyclic loading. The calculations have been carried out with the molecular dynamic modeling. The cyclic loading is modeled by a periodical shift of a movable clamp along the X axis. The calculations are performed for the maximal clamp shift in respect to the equilibrium state, which corresponds to the relative deformation (equal to 0.3%). Frequencies varied from 0.085 THz to 10 THz. It has been discovered that both the dramatic growth of the maximal dispersion of atomic planes, and the dramatic growth of amplification of the maximal dispersion of atomic planes can be used as an index of the irreversible transformation of the crystal structure in the physical system differing from the perfect nanosized crystal. General behavior of the studied systems more depends on cyclic loading parameters than on the object crystal structure. Under the cyclic loading modeled with the aid of the periodical shift of the movable clamp, the frequency makes the critical impact on the results.
