The proposed methodology is a necessary tool for the reasoned use of material properties databases in the Deform-3D program when studying various processes of plastic forming. It is shown that in constructing the databases, various models of hardening of the deformable body were used. In particular, linear and power relationships between stress and strain were used. This allows you to more accurately determine the scope of stress-strain diagrams offered by the Deform-3D program. The stress-strain state diagrams are established for such important materials used in production as AISI-316 corrosion-resistant steel (analogue 12Kh18N9T), Ti-6AL-4V titanium alloy (VT-6 analogue), AL-5056 aluminum alloy (AMg5 analogue) and AISI-2024 (D16T analogue).
