Сформулирована математичеческая модель, описывающая данный процесс в одномерном и двумерном случае. Предложен численный алгоритм, позволяющий проводить математическое моделирование рассматриваемых процессов. Проведена серия вычислительных экспериментов по высокоскоростному нагружению образцов из обеденного урана. Исследована динамика локализационного процесса в зависимости от начальной скорости пластической деформации. Получены значения полей температур, скоростей, напряжеий и деформаций. Исследовано влияние размерности задачи на ряд важнейших характеристик локализационного процесса.</p></abstract><trans-abstract xml:lang="en"><p>The processes of plastic shear localization in DU-0.75Ti alloy samples subjected to high-speed shear are considered. A mathematical model describing this process in the 1D and 2D cases is formulated. A numerical algorithm for the mathematical modeling of the processes under consideration is proposed. A series of computational experiments on high-speed loading of DU samples is carried out. The localization process dynamics depending on the initial rate of plastic shear is investigated. The values of the temperature, velocity, stress, and shear fields are obtained. The influence of the problem dimension on some of the most important characteristics of the localization process is investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полоса адиабатического сдвига</kwd><kwd>локализация деформации</kwd><kwd>пластичность</kwd><kwd>разрушение материалов</kwd><kwd>моделирование</kwd><kwd>метод конечных объемов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adiabatic shear band</kwd><kwd>shear localization</kwd><kwd>plasticity</kwd><kwd>material failure</kwd><kwd>modeling</kwd><kwd>finite volume method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект № 21-71-00102).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rittel D. // Mater.
