cae case studies: hexagonal forming analysis

• Problem: A hollow circular pipe has to be formed into a hexagonal pipe
• The system consists of upper die, lower die and the metal sheet in between the two.
• Lower die was held fixed while upper die was given an enforced displacement.
• Both the upper and lower dies were considered rigid while sheet was considered flexible.
• Solid elements were used to model the metal sheet for accuracy in results, wile the rigid dies were modeled with shell elements.
• Large displacement and large strain options turned on
• Multi-linear Stress vs. Strain curve used.
• Spring back incorporated
