Изучено влияние пористости на демпфирующие и жесткостные свойства композита. Получено оптимальное значение пористости,обеспечивающее максимум декремента колебаний при значимом уровне нагрузки на образец. Приведены результаты численного расчета декремента для композита из хромоникелевой пористой стали.</p></abstract><trans-abstract xml:lang="en"><p>The maximum value of the vibration decrement of a porous metal composite made using 3D technology is determined. The influence of porosity on the damping and stiffness properties of the composite is studied. The optimal porosity value is obtained, which provides a maximum of the vibration decrement at a significant load level on the sample. The results of numericalcalculation of the decrement for a composite made of chromium-nickel porous steel are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>амплитуда напряжений</kwd><kwd>декремент</kwd><kwd>демпфирующие свойства</kwd><kwd>метал- лический пористый композит</kwd><kwd>статистическая модель.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress amplitude</kwd><kwd>decrement</kwd><kwd>damping properties</kwd><kwd>metallic porous composite</kwd><kwd>statistical model.</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">Хусу А.
