Polymer unidirectional composite laminate panel behavior with interlaminate defects under action of different dynamic loads is consider. Methods. Normal modes and eigenvalues of rectangular composite panels in the presence multiple delamination different sizes ellipsoidal form are calculated. The dependences of the maximum deflections from the frequency of the stationary pressure field action are constructed. Distribution field of panels plies failure index under action of nonstationary pressure field by using different failure criteria for composites is determined. Results. Modeling methodology composite panels behavior in the presence multiple interlaminar defects under action of different dynamic loads is developed. Analysis of failure panel with the use of different failure criteria for composites is carried out.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. Основная задача состояла в рассмотрении поведения прямоугольной слоистой панели из однонаправленного полимерного композиционного материала (ПКМ) при наличии межслоевых дефектов под действием динамических нагрузок различного характера. Методы. В ходе исследования рассчитаны формы собственных колебаний прямоугольной композитной панели при наличии множественных расслоений в форме эллипсов различных размеров. Построены зависимости максимальных прогибов от частоты воздействия стационарного поля давления. Определены поля распределения индексов разрушения слоев панели под действием нестационарного поля давления с помощью различных критериев разрушения (применительно к ПКМ). Результаты. Проведен анализ разрушения панели с использованием различных критериев разрушения изделий из композитных материалов. По результатам исследования разработана методика моделирования поведения композитных панелей при наличии множественных межслоевых дефектов при воздействии динамических нагрузок различного характера.</p></trans-abstract><kwd-group xml:lang="en"><kwd>composite panel</kwd><kwd>composite failure criteria</kwd><kwd>interlaminar defect</kwd><kwd>nonstationary load</kwd><kwd>numerical modeling</kwd><kwd>finite element method (FEM)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>композитная панель</kwd><kwd>критерии разрушения композитов</kwd><kwd>межслоевой дефект</kwd><kwd>нестационарная нагрузка</kwd><kwd>численное моделирование</kwd><kwd>метод конечных элементов (МКЭ)</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Medvedskiy A.L., Martirosov M.I., Khomchenko A.V.
