Экспериментальные данные для созданных композитов получены методом индентирования. Идентификация механических свойств вязкоупругих композиционных материалов на основании экспериментально полученных диаграмм «нагрузка – проникновение» проведена на основе созданного вычислительного алгоритма. Представлены результаты идентификации параметров модели Прони по экспериментальным кривым ползучести, которые получены в рамках метода микроиндентирования. Идентификация параметров модели осуществлена гибридным методом на основе генетического алгоритма и метода Нелдера – Мида. Такой подход обеспечивает устойчивую схему определения искомых параметров. Представленный подход к изучению механических свойств материалов эффективен при идентификации вязкоупругих свойств композиционных покрытий. </p></abstract><trans-abstract xml:lang="en"><p>A complex theoretical-experimental research has been carried out for studying effect of micron particles of magnesium oxide and boron carbide filler on the viscoelastic properties of epoxy-diane resin composites. Experimental data for the created composites were obtained by indentation method. Identification of mechanical properties of viscoelastic composites on the basis of experimentally obtained diagrams "load-penetration" is carried out on the basis of the created computational algorithm. The results of identification of the Prony's model parameters from experimental creep curves, which were obtained within the framework of the micro indentation method, are presented. The identification of the model parameters was carried out by a hybrid method based on the genetic algorithm and the Nelder – Mead method. This approach provides a stable scheme for the determination of the sought parameters. The presented approach to the study of mechanical properties of materials is effective in the identification of viscoelastic properties of composite coatings. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>композит</kwd><kwd>микронные частицы</kwd><kwd>вязкоупругость</kwd><kwd>индентирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite</kwd><kwd>micron particles</kwd><kwd>viscoelasticity</kwd><kwd>indentation</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">Люкшин, Б.
