A short history of finite element applications to shell buckling is given. The finite element method is used in its matrix formulation. The elastic stiffness matrixes in the local coordinate system of the membrane element are defined in their general form. The out-of-plane geometric stiffness matrix for the plate along the same lines is derived</abstract><trans-abstract xml:lang="ru"><p>В статье рассматривается расчет на прочность и устойчивость в геометрической нелинейной постановке для синусоидальных велароидальных оболочек под действием собственного веса и равномерно распределенной нагрузки. Приводится краткая история применения метода конечного элемента для изучения потери устойчивости оболочки. Метод конечного элемента используется в матричной формулировке. Эластичная матрица жесткости в локальной системе координат мембранного элемента определяется в общем виде. Получена матрица геометрической жесткости вне плоскости для пластины вдоль тех же линий.</p></trans-abstract><kwd-group xml:lang="en"><kwd>sinusoidal velaroidal surfaces</kwd><kwd>nonlinear buckling analysis</kwd><kwd>linear elastic stiffness matrices</kwd><kwd>normal stiffness</kwd><kwd>geometric stiffness matrix</kwd><kwd>chain rule differentiation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синусоидальные велароидальные оболочки</kwd><kwd>расчет на устойчивость в нелинейной постановке</kwd><kwd>линейная матрица упругой жесткости</kwd><kwd>нормальная жесткость</kwd><kwd>геометрическая матрица жесткости</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">Mihailescu M., Horvath I.
