The finite element modeling of the representative bulk in the stress-strain state conforming to the operation conditions is considered. The calculation methods of polymer composites high-cycle fatigue is based on it. The calculations are carried out in the paper. The unidirectional reinforced composite obtained through thermal curing of the glass-reinforced epoxide is studied. Mechanical properties of such materials (including fatigue life) to quite a great extent depend on the manufacturing technology. The calculation permitting to estimate changing strength properties for fatigue life under the breach of the technology requirements to the composite components percent is resulted.</p></abstract><trans-abstract xml:lang="ru"><p>Расчёт на усталость играет важную роль при проектировании работающих под действием переменной нагрузки деталей и узлов из композитных материалов. Рассматривается конечноэлементное моделирование представительного объёма материала, находящегося в напряжённо деформируемом состоянии, соответствующем эксплуатационным условиям. На этом основана методика расчёта полимеркомпозитов на многоцикловую усталость. В работе проведены расчёты. Исследуется однонаправленный армированный композиционный материал, полученный термическим отверждением эпоксидного связующего, усиленного стекловолокном. Механические свойства материалов такого рода (в том числе усталостная долговечность) в весьма значительной степени зависят от технологии изготовления. В работе приведён расчёт, позволяющий оценить изменение прочностных свойств на усталостную долговечность при нарушении технологических требований к процентному содержанию компонентов композита.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композитный материал</kwd><kwd>многоцикловая усталость.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite</kwd><kwd>high-cycle fatigue.</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">Kim Hyo Jin.
