The paper presents a calculation model for simulation the technological process of inductive bending of tubes. In the case of an incorrect combination of geometric bending parameters (pipe diameter, bend radius and pipe wall thickness), the corrugation of the inner part in the pipe bend occurs. The proposed calculation model for the ADINA FE software allows for a relatively short time and at low cost to predict the emergence of corrugation.
