Построена математическая модель и проведено теоретическое исследование напряженного состояния ОФ при отсутствии в ней связи между слоями в многослойном композите. Рассмотрена сложная трехкомпонентная система (жидкий металл, твердый металл, керамическая оболочковая форма). Твердый металл и ОФ считаются изотропными. Для решения поставленной задачи применялись теория малых упругопластических деформаций и уравнения теплопроводности, а также апробированные численные методы. Эволюция НДС в оболочковых формах прослеживается по временным шагам. Толщина затвердевающего металла определяется из уравнения межфазового перехода. Рассмотрен процесс нагрева осесимметричной ОФ при заливке в нее жидкого металла. Напряженное состояние оценивалось по возникающим в ОФ напряжениям и перемещениям. В процессе охлаждения жидкого металла на контакте оболочковой формы с опорным наполнителем (ОН) возможен отход поверхности между ними. В этом случае решается контактная задача. С учетом составленного алгоритма решения задачи с использованием разработанных численных схем и программных комплексов выполнены расчеты для случая полного скольжения слоев. Полученные результаты численных расчетов представлены в виде эпюр и графиков. Приведен подробный анализ полученных результатов. Показана несостоятельность ранее высказанной идеи о применимости скольжения между слоями в многослойном композите с позиции снижения его напряженного состояния. Результаты исследований могут быть полезны при расчетах других функциональных многослойных оболочечных систем.</p></abstract><trans-abstract xml:lang="en"><p>The process of evolution of the stress-strain state (SSS) of a multilayer shell mold (SM) is modeled at properties change between layers during cooling of poured steel casting. A mathematical model was constructed and a theoretical study of the stress state of the SM was carried out in absence of connection between the layers in a multilayer composite. The article describes a complex three-component system: liquid metal, solid metal, and ceramic SM. Solid metal and SM are considered to be isotropic. To solve this problem, the authors used the theory of small elastic-plastic deformations and equations of thermal conductivity, as well as proven numerical methods. Evolution of SSS in SM was traced by time steps. Thickness of the solidifying metal was determined through the equation of interphase transition. The article considers the process of heating an axisymmetric SM when pouring liquid metal into it. Stress state was estimated by stresses and displacements that occur in SM. At SM contact with support filler (SF), SM surface move away from the SF is possible during cooling of liquid metal. In this case, contact problem is solved. Taking into account the compiled algorithm for solving the problem, calculations were performed for the case of complete sliding of layers using developed numerical schemes and software complexes. Obtained results of numerical calculations are clearly displayed by graphic illustrations in form of plots and graphs. Detailed analysis of the obtained results is given. There is inconsistency of the previously expressed idea about the applicability of sliding between layers in a multilayer composite from the position of reducing its stress state. The research results can be useful in calculations of other functional multilayer shell systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>литье по выплавляемым моделям</kwd><kwd>оболочковая форма</kwd><kwd>напряженное состояние</kwd><kwd>моделирование</kwd><kwd>трещинообразование</kwd><kwd>контактная связь</kwd><kwd>внутренние слои</kwd><kwd>напряжение</kwd><kwd>перемещение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>casting by investment models</kwd><kwd>shell mold</kwd><kwd>stress state</kwd><kwd>modeling</kwd><kwd>cracking</kwd><kwd>contact connection of internal layers</kwd><kwd>stress</kwd><kwd>displacement</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Математическое моделирование процессов получения отливок в керамические оболочковые формы / В.И.
