Аннотация (краткое описание)
In this article, the models of steel-copper and steel-aluminum bimetallic wires obtained in the course of computer simulation in Deform program were studied, the main parameters of the stress state (equivalent stress and average hydrostatic pressure) were considered. When considering the equivalent stress, it is found that in the model with an aluminum shell, a fairly uniform distribution of stress is observed over all layers; in the model with a copper shell, due to the intensification of compression of the steel core, the stress distribution in both layers is extremely uneven – in the shell, the stress level decreases sharply in the direction from the outer layers to the inner ones. When considering the average hydrostatic pressure, it is found that when the aluminum shell changes to copper, the hydrostatic pressure in both layers increases in absolute values, which is a consequence of an increase in the overall level of deformation resistance.DOI
