Modeling of mechanical interaction between filler particles and binder in polymer-silicate nanocomposites under finite macrodeformation

Abstract: 5УДК 539.42 ЧИСЛЕННЫЕ МОДЕЛИ ДИНАМИКИ РАЗРУШЕНИЯ В.А. БратовИнститут проблем машиноведения РАН, С.-Петербург, 199178, Россия В работе подробно рассмотрены проблемы использования критерия инкубационного времени в качестве критерия хрупкого разрушения в конечно-элементных расчетах. Приведен ряд примеров численных расчетов задач динамики разрушения с использованием критерия инкубационного времени. Доказана применимость такого подхода для предсказания инициации, развития и остановки динамического разрушения.Ключев… Show more

“…As a result there is a swelling of the mineral crystallite, but in this case there is no loss order in the arrangement of its layers. In the formation of exfoliated nanocomposite polymer molecules penetrate into the gaps between the layers of tactoids, and move apart them so dramatically that there is a complete destruction of the tactoids, and silicate plates previously parallel acquire a random orientation [69,179].…”

“…As a result there is a swelling of the mineral crystallite, but in this case there is no loss order in the arrangement of its layers. In the formation of exfoliated nanocomposite polymer molecules penetrate into the gaps between the layers of tactoids, and move apart them so dramatically that there is a complete destruction of the tactoids, and silicate plates previously parallel acquire a random orientation [69,179].When formed exfoliated nanocomposite, polymer molecules not only penetrate into the space between the layers of tactoids but they also force them to interact with each other. Thus, the structure collapses, and at the same time the silicate plates lose its orientation in space and are randomly distributed in the bulk material.…”
