На основе анализа полных волновых профилей, зарегистрированных с помо-щью лазерного интерферометра VISAR в процессе ударно-волнового нагруже-ния образцов сплава АМг6, исследуются закономерности выделения упругого предвестника, изменение его амплитуды при распространении упругопластичес-кого фронта в образцах при нагружении ударной волной разной интенсивности. Измерены критические напряжения, приводящие к откольному разрушению образцов в зависимости от ско рости деформирования при разгрузке.
Influence of small additives of fullerene, graphene oxide, and their combinations in the ratio of 85 : 15 on the structure and mechanical properties of cross-linked polyurethanes under static and dynamic loads has been investigated. Nanocomposite structures have been studied by X-ray diffraction analysis and scanning electron microscopy. It is shown that the presence of carbon nanoparticles in the composite reduces its strength under both static and shock-wave loads. The synergistic effect of the mixture of carbon nanoparticles manifests itself as an increase in the elastic modulus by a factor of 1.25 in comparison with the initial polymer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
