Особенности разрушения пластины из хрупкого материала при взаимодействии с ударником

Abstract

Рассмотрены аспекты повреждения пластин из хрупкого материала при высокоскоростном ударе. Численный анализ напряженного состояния пластины при ударе показал, что в зоне контакта возникают значительные растягивающие напряжения, определяющие возможность откола и образования радиальных трещин. На основании модели эквивалентной пробки построена аналитическая зависимость, позволяющая оценить скорость ударника после пробоя пластины из хрупкого материала. In this paper different aspects of brittle material plate fracture at high velocity impact were investigated. Numerical analysis of contact region showed that there are significant tensile stresses may led to dishing and radial cracks. On the base of equivalent plug's model there was developed analytical formula to estimate residual indenter velocity after penetration of plate made from brittle material Сапожников Сергей Борисович – профессор, доктор технических наук, кафедра прикладной механики, динамики и прочности машин, Южно-Уральский государственный университет.
