Многомасштабное конечно-элементное моделирование трехслойных сотовых композитных конструкций

Abstract

Разработана многомасштабная модель трехслойных сотовых конструкций, позволяющая вычислять эффективные упругие и прочностные характеристики сотовых заполнителей и силовых обшивок, а также рассчитывать напряженно-деформированное состояние конструкции в рамках трехмерной теории упругости неоднородных сред. На основе трехмерного конечно-элементного моделирования показано, что при четырехточечном изгибе трехслойной cотовой пластины максимальные значения изгибных и касательных напряжений реализуются в зоне приложения нагрузки и действия опор пластины, причем локальные максимумы напряжений превосходят "балочные" значения изгибающих напряжений и касательных напряжений.
