Abstract

The estimation method of deviation from the circular shaped cross-section in the shaping cosine shaped fittings, bend with pipe shell blank. The method is based on the energy stability criterion and experimental and calculated dependences of stress-strain state. Initial data for calculation are geometric parameters of the product and material properties as an rate of strain hardening.
