С использованием программной системы конечно-элементного анализа ANSYS получены численные значения напряжений на границах раздела фаз феррит-перлит, графит-феррит, а также внутри графитного включения. Проанализировано распределение напряжений в исследуемых структурах и обнаружены зоны локального увеличения напряжений. Результаты моделирования сопоставлены с металлографическим анализом и фрактограммами. Полученные результаты могут быть использованы при прогнозировании зон разрушения в изделиях из чугуна. </p></abstract><trans-abstract xml:lang="en"><p>The computer modeling of the strain distribution in the structure of ductile iron with ferrite-pearlite matrix and inclusions of spherical graphite dependence on increasing degree of deformation during direct hot extrusion was researched. Using a software system of finite-element analysis ANSYS the numerical values of the strains at the phase boundaries: ferrite-perlite, graphiteferrite and also inside the graphite inclusions were defined. The analysis of the strain distribution in the investigated structures was performed and local zones of increased strains were discovered. The results of modeling are compared with metallographic analysis and fracture patterns. The obtained results could be used in the prediction of fracture zones in the cast iron products. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>горячая пластическая деформация</kwd><kwd>высокопрочный чугун</kwd><kwd>структура</kwd><kwd>металлическая матрица</kwd><kwd>включения графита</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hot plastic deformation</kwd><kwd>ductile iron</kwd><kwd>structure</kwd><kwd>metal matrix</kwd><kwd>inclusion of graphite</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">Fundamentals of Materials Science and Engineering: An Integrated Approach / William D.
