Численный анализ критического давления в тонкостенной цилиндрической оболочке, содержащей мягкую прослойку

Abstract

Проводится численный анализ критического давления в тонкостенных цилиндрических оболочках при нагружении их внутренним давлением и осевой силой, с использованием авторских математических моделей напряженно-деформированного состояния таких оболочек. Предполагается, что оболочки содержат слои (прослойки) из менее прочного материала. На основе этих моделей созданы программы, позволяющие находить критическое внутреннее давление в оболочках в зависимости от механических и геометрических параметров и условий нагружения.

The numerical analysis of critical pressure in thin-walled cylindrical shells with use of author's mathematical models of the stress-strained state of such shells is made at a loading their intrinsic pressure and an axial thrust. It is supposed, that shells contain layers from less strong material. On the basis of these models the programs are created, allowing to find a critical intrinsic pressure in shell depending on mechanical and geometrical parameters and conditions of loading.
