Based on a thermodynamic approach, the objective is the evaluation of the specific energy of interfacial delamination in a multi-layer composite material under dynamic loading causing damage to it by cracking. For modeling of dynamic loading, it was used an experi- mental device based on the principle of the Charpy test which is to measure the residual en- ergy of a mass movement following a shock at speeds generally between 1 and 4 m/s, on a test piece cut of standardized dimensions requested in bending. Some of the available energy is consumed by rupture of the test piece. The results of this work showed that for a dynamic test, the fracture energy is function of the speed and impact energy of fall of the load. These results may be useful in the design of multilayer composite structures subjected to dynamic loads</abstract><trans-abstract xml:lang="ru">Работа посвящена экспериментальному изучению полиэфирного древесного ком- позита под действием динамической нагрузки. В основе лежит термодинамический подход, целью исследования является оценка удельной энергии межфазного расслоения в многослойных композиционных материалах в условиях динамической загрузки, т.е. оценка влияния этих нагрузок на растрескивание образца. Для моделирования динами- ческой нагрузки, было использовано экспериментальное устройство, основанное на принципе испытании по Шарпи (Charpy test). Эксперимент заключался в измерении остаточной энергии движения тела в результате ударного изгибного воздействия (со скоростью в среднем от 1 м/с до 4 м/с) на предварительно расщепленный образец стан- дартных размеров. Некоторая часть имеющейся энергии потребляется для разрушения образца. Исследования показали, что при динамических испытаниях энергия разруше- ния является функцией скорости и энергии удара от падения нагрузки. Эти результаты могут быть полезными при разработке многослойных композитных конструкций, нахо- дящихся по действием динамической нагрузки</trans-abstract><kwd-group xml:lang="en"><kwd>polyester-wood composite</kwd><kwd>dynamic loading</kwd><kwd>fracture energy interfacial delamination</kwd><kwd>specific energy of delamination</kwd><kwd>Charpy test</kwd><kwd>cracking</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полиэфирно-древесный композит</kwd><kwd>динамическое нагруже- ние</kwd><kwd>удельная энергия межфазного расслоения</kwd><kwd>испытание по Шарпи</kwd><kwd>трещины</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lemaitre J, Chaboche J-L (1985), Mecanique des materiaux solides, Paris, Dunod, 307 p.</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>Bui HD (1978), Mecanique de la rupture fragile, Paris, Masson, 423 p.</mixed-citation></ref><ref id="B3"><label>3.</label><mixed-citation>Labbens RC (1980), Introduction a la mecanique de la rupture, Paris, Pluralis, 217 p.</mixed-citation></ref><ref id="B4"><label>4.</label><mixed-citation>Hopkinson D (1914), A method of measuring the pressure produced in the detonation of high explosives or by the impact of bullets, Phil., Trans.
