Актуальность работы обусловлена необходимостью разработки вычислительно эффективных моделей, позволяющих учитывать особенности армирования железобетона при ударных воздействиях умеренной скорости. Целью исследования является разработка и обоснование смесевой математической модели железобетона, предназначенной для прогнозирования параметров проникания и характера локального разрушения преграды. В работе использован численный подход, основанный на представлении железобетона как гомогенной двухфазной среды, учитывающей совместную работу бетонной матрицы и арматуры. Калибровка модели выполнена по опубликованным экспериментальным данным для удара составного стального ударника массой около 330 кг со скоростью порядка 30 м/с по железобетон-ной плите. В результате расчетов получены кинематические параметры движения ударника, глубина внедрения и характер разрушения преграды. Показано, что предложенная модель позволяет удовлетворительно описывать процесс пробивания железобетонной плиты, воспроизводя основные особенности локального разрушения. Сделан вывод о перспективности применения смесевого подхода для инженерной оценки ударной стойкости железобетонных конструкций.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers the problem of local failure of a reinforced concrete slab subjected to impact by a heavy steel projectile. This problem is of practical importance in the design and safety assessment of protective structures, including facilities in the nuclear industry and other special-purpose structures. The relevance of the study is determined by the need for computationally efficient models capable of accounting for the influence of reinforcement on penetration parameters and damage patterns under moderate velocity impact loading. The aim of the study is to develop and justify a mixture-based mathematical model of reinforced concrete for predicting local damage and penetration depth. A numerical approach is used in which reinforced concrete is represented as a homogeneous two-phase medium reflecting the combined action of the concrete matrix and reinforcing steel. The model is calibrated using published experimental data for the impact of a composite steel projectile with a mass of about 330 kg and a velocity of about 30 m/s on a reinforced concrete slab. The calculations made it possible to determine the kinematic parameters of projectile motion, penetration depth, and the main features of target failure. The results show that the proposed model reproduces the main characteristics of reinforced concrete slab perforation with satisfactory accuracy and can be used for engineering assessment of the impact resistance of reinforced concrete structures. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетон</kwd><kwd>ударное воздействие</kwd><kwd>тяжелый стальной ударник</kwd><kwd>проникание</kwd><kwd>локальное разрушение</kwd><kwd>смесевая модель</kwd><kwd>математическое моделирование</kwd><kwd>численный расчет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforced concrete</kwd><kwd>impact loading</kwd><kwd>heavy steel projectile</kwd><kwd>penetration</kwd><kwd>local failure</kwd><kwd>mixture model</kwd><kwd>mathematical modeling</kwd><kwd>numerical simulation</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">Young C.W.
