“…We show that the EBAM-manufactured AlSi12 alloy represents a multi-level composite material. Some of the features of the deformation and fracture of particle-reinforced composites were reported in our earlier works [34][35][36]. We examined the influence of the volume fraction, spatial distribution of reinforcing particles, and strength and plasticity characteristics of the matrix and particle materials on the macroscopic response of the composite.…”

“…Для такой среды строится система определяющих соотношений с учетом условий для напряжений и деформаций на внутренних границах раздела (интерфейсах). В общем случае такая система уравнений решается численно, а усреднение получаемых результатов для представительных мезообъемов позволяет оценивать эффективные свойства композита [7][8][9][10][11][12][13]. Несмотря на хорошо известные преимущества (возможность явного учета микроструктуры и особых свойств интерфейсов), непосредственная компьютерная гомогенизация является вычислительно крайне затратной процедурой вследствие необходимости проведения многопараметрического исследования для определения однозначного соответствия внутренней структуры и макроскопических свойств материала.…”

“…These have been studied in some depth. [14][15][16][17][18] They certainly have the potential to be significant, since a typical difference in thermal expansivity between particle and matrix is about 20 microstrain K À1 , so that a temperature drop of, say, 500 K will generate a (large) misfit strain of about 10 millistrain. In fact, since the resulting stresses are, on average, purely hydrostatic (compressive in the particles and tensile in the matrix), they tend to have less effect on the behavior than for MMCs that incorporate directionality, such as aligned fiber composites.…”
