Abstract
The results of 3D modeling of the distribution and accumulation of dislocations and low-angle boundaries in the volume of a layered metal-intermetallic composite under uniaxial compression are obtained. The calculations are performed using a synthesis model of dislocation kinetics and mechanics of a deformable solid. The model is preliminarily tested on a single-phase intermetallic compound and pure metal, which shows a good agreement between the calculated values and the earlier obtained experimental results. The patterns of stress distribution, plastic deformation intensity, dislocation density, and low-angle boundaries density in the plane of the central longitudinal section of a deformed rectangular sample of a layered metal-intermetallic composite are presented. The inhomogeneities of internal stresses and strength properties of the selected-configuration layered metal-intermetallic composite under compression are evaluated.
