Индентором является цилиндр с заостренной конической частью. Инденторы и преграды изготовлены из стали. В результате оцифровки графиков исследуемых зависимостей получены интерполяционные формулы распределения энергий упругих и пластических деформаций в контактной зоне. В отличие от предыдущей публикации, где рассматривались три варианта угла заострения конической головной части индентора, в данной работе значительно увеличен диапазон изменения данных углов.</p><p>Полученные результаты можно использовать при проектировании составных многостержневых пуансонов и матриц для обработки листовых материалов давлением, а также при разработке силовых и геометрических параметров ударных инструментов для гидромолотов.</p></abstract><trans-abstract xml:lang="en"><p>The article is a continuation of the study of dynamic dependencies between force and depth of introduction of conical indenters into barriers. The indenter is a cylinder with a pointed conical part. Indenters and barriers are made of steel. As a result of digitization of graphs of investigated dependencies, interpolation formulas of distribution of energies of elastic and plastic deformations in contact zone are obtained. Unlike the previous publication, which considered three variants of the angle of sharpening of the conical head part of the indenter, in this work the range of change of these angles is significantly increased.</p><p>The obtained results can be used in the design of composite many rod punches and matrices for pressure treatment of sheet materials, as well as in the development of power and geometric parameters of impact tools for hydromolots.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>упругие и пластические деформации</kwd><kwd>ударная сила</kwd><kwd>цилиндрический индентор с конической головной частью</kwd><kwd>технология бесформенной многоточечной формовки</kwd><kwd>разрушение горных пород</kwd><kwd>инструменты для гидромолота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elastic and plastic deformations</kwd><kwd>impact force</kwd><kwd>cylindrical indenter with conical head part</kwd><kwd>technology of formless multipoint moulding</kwd><kwd>destruction of rocks</kwd><kwd>tools for hydromolot</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">Айзикович С.
