“…Второе направление -это анализ динамики формирования различных дисло-кационных структур в условиях внешних воздействий в рамках двумерной ньютоновской динамики [39][40][41][42][43]. В последние годы развитие этого направления свя-зано с описанием пластической деформации вблизи границ зерен [42,43], клиновых дисклинаций [44][45][46][47][48][49][50][51][52][53][54], трещин [55][56][57][58][59], пор [59][60][61][62][63] и включений [64][65][66].…”

“…This approach is a natural extension of the well-known 2D discrete dislocation dynamics [33-38] (see also [39] for more references) to the case of large plastic deformations. It is also worth noting that until now, the 2D D 4 -approach has been applied to simulations in quasi-static conditions under which the fragmentation process develops during hundreds of seconds [28][29][30][31][32]. In the shock-loading experiments of interest [14,15], the duration of the impact impulse was of about 650 ns and, therefore, http://dx.…”

“…A great progress in its understanding was achieved after introduction of the concept of partial disclinations which are treated as the principal carriers of plastic deformation in metallic materials at the fragmentation stage [20][21][22][23][24]. In recent years, an effective tool in theoretical modeling of partial disclinations and fragmentation development has become the approach of 2D discrete dislocation-disclination dynamics (the D 4 -approach) which describes the collective behavior of straight dislocations interacting with partial disclinations and, moreover, forming these disclinations [23,[25][26][27][28][29][30][31][32]. This approach is a natural extension of the well-known 2D discrete dislocation dynamics [33][34][35][36][37][38] (see also [39] for more references) to the case of large plastic deformations.…”
