Моделирование пробития панели компактным ударником

Моделирование пробития панели компактным ударником

Abstract

Рассматривается проникание сферического ударника в плоскую преграду при различных скоростях соударения. Сформирована конечно-элементная модель деформирования пластины при высокоскоростном воздействии сферического ударника, позволяющая получать характеристики напряженно-деформированного состояния пластины при пробивании с достаточной точностью и при приемлемых затратах времени ЭВМ. Результаты расчета предельных значений толщины пробития пластины удовлетворительно согласуются с известными экспериментальными данными.
