Abstract
The strain energy in nanocomposites based on porous anodic aluminum oxide and filamentary nanoparticles of Cu, Ag, and Au is simulated numerically. The results allow us to estimate the contribution from mechanical stresses produced upon heating, due to differences between the thermal coefficients of the linear expansion of elements of heterogeneity upon a change in the melting point of spatially confined metallic filamentary nanoparticles. The dependence of the energy of deformation on the structural parameter associated with the concentrations of Cu, Ag, and Au fibers in the considered nanocomposite systems is studied. It is found that at temperatures close to 1000°C, the contribution from mechanical stresses to the change in melting point, quantitatively expressed by the studied energy characteristic, is negligible in comparison to the contribution from the surface.
