A comprehensive study of shells with corrugated inner surface

This paper presents the results of a comprehensive assessment of the manufacture of pipes with corrugated inner surface. It examines the technological force, the stressed and deformed states, the probability of defects during corrugation of the pipe at different depths with the help of a rotating working mandrel and the plastic deformation caused by it. The analysis was performed using special QForm software. The study provides the graphs of force, distribution of stress and strain intensity and the probability of defects occurring in the part during corrugation.
