Bending moment for pipes at various strain levels
The attached chart is used in the offshore pipeline industry where plastic deformation and straightening is common with e.g. reeling in cases up to 2.5%. DNV specifications allows up tp 5% by using material with the additional requirement P...- Tor Person

Bending moment for pipes at various strain levels
Allowable moment (M) for elastic deformation is calculated as M = Section modulus x allowable stress. How to calculate the moment for plastic deformation e.g. in a bending machine?https://files.engineering.com/getfile.aspx?folder=f973e879-ae02-4a6b-a9ee-001be79755f7&file=stress_strain.jpg- Tor Person
