“…In stark contrast with these approaches which emphasize on individual atoms or dislocation segments, a number of researchers have advocated the use of a modeling strategy that focuses on dislocation density (Walgraef and Aifantis, 1985;Groma, 1997;Acharya, 2001;Arsenlis et al, 2004;Zhou and Sun, 2004;Evers et al, 2004;Yefimov and Van der Giessen, 2005;Pontes et al, 2006;Ma et al, 2006;Hochrainer et al, 2007;Lee et al, 2010;Watanabe et al, 2010;Alankar et al, 2011;Hirschberger et al, 2011;Bargmann et al, 2011;Liu et al, 2011;Shanthraj and Zikry, 2012;Engels et al, 2012;Aghababaei and Joshi, 2013;Li et al, 2014). Unlike DDD which becomes handicapped at high strains, such a strategy would be well suited for large-strain problems with high quantities of dislocations, since any amount of dislocations can still be represented a dislocation density.…”

“…Во многих моделях использу-ется разделение дислокаций на различные типы (мобильные -иммобильные [34,41,42,43,44,68,76,98,99], статистически накопленные и геометрически необходимые [95]). …”

“…Модель дислокационной динамики для описания поведения монокристаллов α-Fe и сплавов Fe-Ni, Fe-Cr, основанная на построении системы эволюционных уравнений для плотностей различных типов дислокаций, представлена в работе [76].Основным источни-ком дислокаций полагаются источники Франка-Рида, представленные в виде конечных дислокационных сегментов; общая плотность дислокаций разделяется на мобильные и иммобильные. В рамках дислокационного подхода подвижность винтовых дислокаций относительно краевых дислокации считается незначительной.…”

“…Several coupling attempts have also been made by many researchers to understand the multiscale nature of deformation process. Such attempts include either coupling Discrete Dislocation Dynamics (DDD) to the crystal plasticity framework [26][27][28][29], molecular dynamics to discrete dislocation dynamics [30,31] or molecular dynamics to finite element method [32][33][34]. An attempt to combine all the three length scales was made by Groh et al [35] and Chang et al [36].…”
