Abstract
Results of studies on the reliability of mathematical modeling of metal plastic flow using the finite element method implemented in various software products are presented. The limitations of the finite element method and their influence on the description of deformation processes occurring during intensive shaping of a workpiece are analyzed. Special attention is paid to the study of regions with complex metal flow. A comparison of mathematical modeling results obtained using MSC Simufact.Forming, Transvalor Forge, SFTC DeForm, and QuantorForm QForm with parameters of actual products is carried out. It is shown that the results of mathematical modeling performed with the mentioned applied software products for complex metal flow studies are sufficiently reliable.
