Алгоритм основан на методе дискретных элементов со связями, в котором среда представляется в виде набора взаимодействующих частиц. Целью работы является систематическое исследование влияния входных параметров на прочностные характеристики получаемого материала. Приводится серия численных экспериментов для различных комбинаций касательной жесткости, длины связей и коэффициента трения частиц на микроуровне. На основании полученных диаграмм напряжения–деформации вычислены значения модуля Юнга и прочности тела на сжатие. Показано, что предельные нагрузки, выдерживаемые материалом, показывают линейный рост при увеличении длины связей и касательной жесткости и квадратичную зависимость при увеличении коэффициента трения. Для модуля Юнга показано наличие роста при увеличении всех варьируемых параметров, однако характер роста представляется невозможным установить при использованном в работе количестве статистических реализаций.</p></abstract><trans-abstract xml:lang="en"><p>This paper provides a description and software implementation of an algorithm for numerical simulation of uniaxial loading of porous media. The algorithm is based on the method of bonded discrete elements, in which the environment is represented as a set of interacting particles. The purpose of this study is to systematically study the influence of input parameters on the strength characteristics of the resulting material. A series of numerical experiments is presented for various combinations of tangential stiffness, bond length, and particle friction coefficient at the microlevel. Based on the obtained stress-strain curves, the values of Young's modulus and compressive strength of the body were calculated. It is shown that compressive strength of the material shows a linear increase with increasing bond length and tangential stiffness, and a quadratic dependence with increasing friction coefficient. Young's modulus tends to increase for all varied parameters. However, it seems impossible to establish any specific dependencies using the number of statistical realizations used in the work.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод дискретных элементов</kwd><kwd>одноосное нагружение</kwd><kwd>гранулированные материалы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>discrete element method</kwd><kwd>uniaxial loading</kwd><kwd>granular materials</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках проекта ФНИ FWZZ-2022-0022 и при поддержке Российского научного фонда, грант № 21-71-20003.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out as part of government assignment to the Russian Academy of Sciences in basic research, Project FWZZ-2022-0022, and supported by the Russian Science Foundation, Project No. 21-71-20003.</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">Bordia R.K., Kang S.J.L., Olevsky E.A.
