Индентором является цилиндр с заостренной конической частью. Инденторы и преграды изготовлены из стали, дюралюминия и латуни. В результате оцифровки графиков исследуемых зависимостей получены интерполяционные формулы распределения энергий упругих и пластических деформаций в контактной зоне. Полученные результаты можно использовать при проектировании штампов и матриц для обработки материалов давлением, а также при разработке параметров технологических операций при изготовлении профильных деталей из стального и дюралюминиевого листового материала.</p></abstract><trans-abstract xml:lang="en"><p>The work analyzes the dynamic and static relationships between force and indentation depth when conical indenters are pressed into various materials. The indenter consists of a cylindrical body with a pointed conical tip. Indenters and targets are fabricated from steel, duralumin, and brass. Through digitization of graphs representing the investigated relationships, interpolation formulas describing the distribution of elastic and plastic deformation energies within the contact zone are derived. The obtained results can be applied in the design of dies and matrices for material forming processes, as well as in the determination of parameters for technological operations during the fabrication of profiled parts from steel and duralumin sheets.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>упругие и пластические деформации</kwd><kwd>цилиндрический индентор с конической головной частью</kwd><kwd>обработка материалов давлением</kwd><kwd>прочность</kwd><kwd>листовая штамповка</kwd><kwd>бесформенная многоточечная формовка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elastic and plastic deformations</kwd><kwd>cylindrical indenter with conical head part</kwd><kwd>processing of materials by pressure</kwd><kwd>strength</kwd><kwd>sheet stamping</kwd><kwd>formless multipoint forming</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">Johnson K.
