Применение МКЭ для решения связанных задач термоупругости нелинейных материалов, чувствительных к виду напряжённого состояния

Abstract

The method of modification of volume four node finite element in the form of a tetrahedron to address problems of thermoelastic materials with essentially nonlinear dependencies of the properties of stress has been considered. The results of calculation of the spherical shell in a physically and geometrically nonlinear and linear statement has been estimated.

Рассмотрена методика модификации объёмного четырёх узлового конечного элемента в виде тетраэдра для решения связанных задач термоупругости материалов с существенно нелинейными зависимостями свойств от вида напряжённого состояния. Приводятся результаты расчёта сферической оболочки в физически и геометрически нелинейной и линейной постановках.
