The theory of the deformability of blanks of a complex profile under conditions of limiting shape formation has been developed and methods for estimating the probability of destruction in the most dangerous areas have been refined; methods for estimating the deformability of blanks under conditions of volumetric stress and complex loading; The methods of estimating the plasticity parameters using two stress-state indicators, taking into account the influence of the first and third invariants of the stress tensor, as well as the second invariant of the stress deviator, have been developed further. With this approach, the shape of the load path is uniquely determined by the conditions for shaping the blanks.
