В качестве модельного материала  использован титанат бария. Показано, что электрокалорический эффект можно регулировать с помощью одноосного сжимающего напряжения. Применение сжимающего напряжения является эффективным подходом для повышения электрокалорического эффекта в  сегнетоэлектрической керамике. Сжимающее  напряжение в рассматриваемой двухслойной магнитострикционно-сегнетоэлектрической  структуре является следствием механически связанных слоев сегнетоэлектрика и  магнитострикционного материала. </p></abstract><trans-abstract xml:lang="en"><p> The influence of uniaxial compression on the electrocaloric effect in a barium titanate-based bilayer was studied using the Landau-Ginzburg thermodynamic approach. Barium titanate was used as a model material. It was shown that the electrocaloric effect can be controlled by uniaxial compression. Application of compressive stress is an effective approach to enhance the electrocaloric effect in ferroelectric ceramics. The compressive stress in the considered magnetostrictive-ferroelectric bilayer is a result of mechanical coupling between ferroelectric and magnetostrictive phases. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическое моделирование</kwd><kwd>электрокалорический эффект</kwd><kwd>магнитокалорический эффект</kwd><kwd>барокалорический эффект</kwd><kwd>мультиферроик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical modeling</kwd><kwd>electrocaloric effect</kwd><kwd>magnetocaloric effect</kwd><kwd>barocaloric effect</kwd><kwd>multiferroic</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 22- 21-20119, https://rscf.ru/project/ 22-21-20119/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Electrocaloric Materials / Editors T.
