Искомые формы представлены двумя нечетными гиперболо-тригонометрическими рядами с коэффициентами, которые должны обеспечить точное выполнение всех условий задачи. Предложено решение однородной бесконечной системы линейных алгебраических уравнений относительно одной последовательности коэффициентов, содержащей в качестве параметра искомую критическую нагрузку, которая находилась методом «стрельбы» в ходе итерационного процесса. Найдены первые три критические нагрузки для квадратной пластинки и представлены их 3D-изображения. Полученные результаты могут быть использованы в расчетах чувствительных элементов различных датчиков в микроэлектронике, биологии и медицине.</p></abstract><trans-abstract xml:lang="en"><p>Antisymmetric forms (A-A) of the stability loss of a highly elastic rectangular plate in which two parallel facesare pinched, and the other two are free (CFCF), under the influence of a compressive load on the pinched faces,are investigated. The desired shapes are represented by two odd hyperbolic-trigonometric series with coefficientswhich should ensure the exact fulfillment of all the conditions of the problem. The problem was reduced to solving ahomogeneous infinite system of linear algebraic equations with respect to a single sequence of coefficients containingas a parameter the desired critical load which was found by “firing” during the iterative process. The first three criticalloads for a square plate are found and their 3D images are presented. The results obtained can be used in calculationsof sensitive elements of various sensors in microelectronics, biology, and medicine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>CFCF-пластинка</kwd><kwd>критические нагрузки</kwd><kwd>антисимметричные формы</kwd><kwd>гиперболо-тригонометрические ряды</kwd><kwd>итерационный метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CFCF-plate</kwd><kwd>critical loads</kwd><kwd>antisymmetric forms</kwd><kwd>hyperbolic-trigonometric series</kwd><kwd>iterative method</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">Сухотерин М.В., Сосновская А.А.
