К таким показателям относятся опасный объем и интегральная повреждаемость. В статье рассмотрены два алгоритма, один из которых основан на построении регулярной ортогональной сетки по потенциально повреждаемой области, второй – на применении метода Монте-Карло к вычислению кратного интеграла от функции локальной повреждаемости. Описаны алгоритмы применения каждого из подходов и проведен анализ их сходимости в зависимости от количества расчетных узлов. Функция локальной повреждаемости в каждой точке среды определялась как отношение действующих напряжений в точке к предельным напряжениям. Действующие напряжения рассчитывались методом граничных элементов. При разработке алгоритмов использовались методы параллелизации вычислений.</p></abstract><trans-abstract xml:lang="en"><p>An analysis of statistical methods used to quantify damageability indicators for solid deformable media is conducted. These indicators include critical volume and integral damageability. The article discusses two algorithms, one based on constructing a regular orthogonal grid over the potentially damaged region, and the other on applying the Monte Carlo method to calculating the multiple integral of the local damageability function. Algorithms for each approach are described, and their convergence is analyzed depending on the number of computational nodes. The local damage function at each point of the material was defined as the ratio of the acting stresses at the point to the ultimate stresses. The effective stresses were calculated using the boundary element method. Parallel computation methods were used in developing the algorithms.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>напряженное состояние</kwd><kwd>повреждаемость</kwd><kwd>опасный объем</kwd><kwd>статистические методы</kwd><kwd>метод Монте-Карло</kwd><kwd>сходимость</kwd><kwd>параллелизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress state</kwd><kwd>damageability</kwd><kwd>critical volume</kwd><kwd>statistical methods</kwd><kwd>Monte Carlo method</kwd><kwd>convergence</kwd><kwd>parallelization</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">Hectors, K.
