The deformation of three-layer elastoplastic beam under the cyclic loading in a temperature field is considered. For the description of kinematics of asymmetrical on the package thickness beam the hypotheses of broken normal are accepted. The method of solving the corresponding boundary-value problems is given. The analytical solutions of thermoelasticity and thermo-elasto-plasticity problems under the direct and reverse loading are received. The numeric analysis is conducted.
Рассмотрено деформирование физически нелинейного трёхслойного стержня при циклическом нагружении в температурном поле. Для описания кинематики несимметричного по толщине пакета стержня приняты гипотезы ломаной нормали. Предложена методика решения соответствующих краевых задач. Получены аналитические решения задач термоупругости и термоупругопластичности при прямом и обратном нагружениях. Проведён численный анализ решений.
