МАТЕМАТИЧЕСКОЕ МОДЕЛИРОВАНИЕ ИССЛЕДОВАНИЯ ТЕРМО- НАПРЯЖЕННОГО В СОСТОЯНИЯ СТЕРЖНЯ ИЗ ЖАРОПРОЧНОГО СПЛАВА

Abstract

On the basis of energy principles, a mathematical model, a computational algorithm and a method with the help of which the thermo-stress-strain state of a rod of a constant cross-section fixed by two ends has been numerically investigated in a combination of the application of a quadratic finite element and three nodes, based on minimizing the total thermal and potential energy of elastic deformation the dependence of the presence of partial heat insulation, heat flow and heat exchange.
