Abstract
The paper covers the effect of material anisotropy on the nature of deformation and geometrical dimensions of the finished capsule made of AD1M aluminum alloy in the drawing process. Metallographic, X-ray diffraction, full-scale production, and computer studies were conducted and the mechanical properties of the material were determined in order to identify the factors of the material anisotropy. Finite element analysis of the drawing process was conducted, where isotropic and macroanisotropic models, together with a model which factored in the microstructure of AD1M aluminum alloy, were considered as the treated material. It was found that only the macroanisotropic model and, to a greater extent, the finite element model which factored in the material microstructure in contrast to the isotropic model, allowed studying the earing process. It was shown that factoring in the sheet material anisotropy in the manufacture of hollow cylindrical parts by die stamping made it possible to determine the nature of metal flow more accurately and realistically and thus determine the final geometry of produced parts and consequently to create a stable process and improve product performance.
