Адекватность упрощенных моделей высокоскоростного деформирования цилиндрических оболочек

Адекватность упрощенных моделей высокоскоростного деформирования цилиндрических оболочек

Abstract

Проведен сравнительный анализ упрощенных математических моделей высокоскоростного упруго-пластического деформирования цилиндрических оболочек, основанный на сравнении с экспериментальными данными. Показано, что нестационарная двухмерная модель должна учитывать динамические свойства материала и температурные параметры.

Comparative analysis of simplified mathematical models of high-speed elasto-plastic strain of cylindrical casings based on comparison with experimental data has been made. A non-stationery two-dimentional model has been shown to consider both the dynamic properties of the material and temperature parameters.
