Использование композиционных материалов в конструкциях и деталях востребовано. Актуальность работы определяется исследованием устойчивости оболочечной конструкции из углепластика. Задача анализа на механическое поведение расположения слоев намотки оболочки остается недостаточно исследованной, хотя имеется опыт в создании геометрических моделей конечно-элементных сеток и исследовании потери устойчивости конструкции, выполненной из оболочки. Поэтому вопрос влияния на форму потери устойчивости при варьировании расположения слоев намотки актуален для их регламентации при различной комбинации углов, так как нет полных данных.</p><p>Цель исследования – выявление расположения слоев намотки, при котором будут действовать максимальная и минимальная критические силы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Объект исследования – цилиндрическая оболочка радиусом 300 мм, высотой 600 мм и толщиной стенки 1,56 мм из восьми слоев углеродного волокна различной ориентации, пропитанного эпоксидной смолой. Моделирование конструкции проводилось с помощью метода конечных элементов. Стенки цилиндрической оболочки моделировались плоскими элементами типа Laminate, учитывающими слои укладки композита. По нижнему торцу цилиндр имел жесткое защемление, по верхнему – прикладывалась осевая сжимающая сила 100 кН. С использованием программного комплекса получены различные варианты потери устойчивости для дальнейшего анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Методом конечных элементов получены данные, описывающие потерю устойчивости цилиндрической оболочки, – коэффициент критической нагрузки при первой форме потери устойчивости, также приведены графики зависимости критической силы от вариантов укладок слоев. В зависимости от величины критической силы и формы потери устойчивости выбраны наиболее и наименее благоприятные варианты укладок слоев в пакете композиционного материала.</p></sec><sec><title>Выводы</title><p>Выводы. Установлено, что ориентация слоев в пакете композиционного материала влияет на форму потери устойчивости и величину критической силы. Зная условия нагружения и закрепления конструкции, можно рационально выбирать ориентацию слоев, что увеличивает критическую силу в 2,25 раза. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. At present, composite materials are widely used in building structures and their components. The relevance of the work is determined by the buckling study of a shell structure made of a carbon fiber reinforced polymer. Despite the available experience in creating geometric models of finite element grids and studying the buckling of shell structures, the task of analyzing the mechanical behavior of shell layers remains insufficiently investigated. Therefore, research into the effects caused by polymer layering variations on a buckling mode appears to be urgent for regulating the layering process at various angle combinations due to a lack of sufficient data.</p></sec><sec><title>Aim</title><p>Aim. The study was aimed at identifying a layering pattern, under which maximum and minimum critical forces operate.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The object of the study involves a cylindrical shell with a radius of 300 mm, a height of 600 mm, and a wall thickness of 1.56 mm made of eight variously-oriented carbon fiber layers impregnated with epoxy resin. The design modeling was performed using the finite element method. The cylindrical shell walls were modeled in terms of Laminate type flat elements, taking into account the composite layers. At the lower end, the cylinder was rigidly fixed and 100 kN axial compressive force was applied to the upper end of the cylinder. Using a software package, the variants of buckling modes were obtained for further analysis.</p></sec><sec><title>Results</title><p>Results. The data, describing the buckling of a cylindrical shell, including the critical load coefficient at the first buckling mode were obtained by the finite element method. In addition, the dependence of a critical force on layering patterns was determined. Depending on the critical force value and the buckling mode, the most and least favorable patterns of layering in a package of a composite material were selected.</p></sec><sec><title>Conclusions</title><p>Conclusions. The orientation of layers in a composite material package affects the buckling mode and the value of critical force. An optimal selection of the layer orientation increases the critical force value by 2.25 times based on the information about the conditions of structural loading and fastening. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>устойчивость</kwd><kwd>композиционный материал</kwd><kwd>критическая сила</kwd><kwd>цилиндрическая оболочка</kwd><kwd>углепластик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>buckling</kwd><kwd>composite material</kwd><kwd>critical force</kwd><kwd>cylindrical shell</kwd><kwd>carbon plastic</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">Rah K., Van Paepegem W., Habraken A.M., Degrieck J.
