Creation of internal protrusion in pipe billet by radial extrusion. Determination of deformed state. Part 3

Key Points

• The study identifies the formulas for calculating accumulated deformations during internal radial extrusion.
• Accumulated deformations were derived based on the plastic flow method, enhancing understanding of pipe billet processing.
• Analysis of internal protrusions provides insights into the deformation patterns of pipe billets under radial extrusion conditions.
• The findings may facilitate advanced techniques in pipe manufacturing and improve production efficiency.
