Получено аналитическое выражение зависимости динамического предела текучести от концентрации призматических дислокационных петель и точечных дефектов. Зависимость динамического предела текучести от концентрации точечных дефектов является немонотонной и имеет минимум. Положение минимума определяется конкуренцией сил динамического торможения дислокаций различными типами структурных дефектов.</p></abstract><trans-abstract xml:lang="en"><p>Within the framework of the theory of dynamic interaction of defects (DID), an analysis of plastic deformation of irradiated metals and alloys under the high-energy impacts is performed. An analytical expression for the dependence of the dynamic yield strength on the concentration of prismatic dislocation loops and point defects is obtained. The dependence of the dynamic yield strength on the concentration of point defects is nonmonotonic and has a minimum. The position of the minimum is due to the competition between the dynamic drag forces of dislocations caused by different types of structural defects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дислокации</kwd><kwd>высокоскоростная деформация</kwd><kwd>облученные металлы</kwd><kwd>радиационные дефекты</kwd><kwd>динамический предел текучести</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dislocations</kwd><kwd>high strain rate deformation</kwd><kwd>irradiated metals</kwd><kwd>radiation defects</kwd><kwd>dynamic yield stress</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abernethy R.
