        <p>В настоящей работе изучаются упругие свойства кристаллического циркония в широком диапазоне давлений с использованием подхода, основанного на первопринципном методе теории функционала электронной плотности. Рассчитаны кривая холодного сжатия и упругие модули гексагональных фаз кристаллического циркония методом деформации--напряжения. Результаты расчетов хорошо согласуются с экспериментальными данными.</p>

        <p>In the present work the elastic properties of crystalline zirconium in a wide range of pressures are studied using the approach based on the first-principles method of the density functional theory. The cold compression curve and elastic moduli of hexagonal phases of crystalline zirconium are calculated by the strain-stress method. The calculation results are in good agreement with the experimental data.</p>
