TRUBITSIN This article explores the possibility of a molecular dynamics method (MMD) for the study of thermal properties of nanostructured periodic materials based on titanium and aluminum. From simulation data for different periodic systems obtained the spectral density of the vibrational States of atoms on the basis of which the calculated temperature dependence of heat capacity for different confi gurations and the infl uence of features of the phonon spectrum on the behavior of low-temperature heat capacity of nanostructured materials. It is shown that the presence of low frequency peaks (up to ~5meV) in the spectrum of fl uctuations leads to the appearance of the maximum in the curve of the temperature dependences of the heat capacity to the cube of the temperature in the region of ~7…12 K. Key words: vibrational density of States, heat capacity, nanostructured material, the method of molecular dynamics. Contacts: E-mail: elena@ftiudm.ru, E-mail: tvy@ftiudm.ru Pp. 64-67.
