Cold bending bending stress curve is what?

Cold-formed steel and welded pipe are all economical cross-section profiles, finished products made of these profiles can reduce weight, reduce costs, increase the mechanical properties of the structure, and has good processability. Wide range of applications. Mainly used in construction, machinery manufacturing, transportation, petrochemicals, power meters, containers, highway guardrail, metal shelves and daily necessities manufacturing and other fields. The past 30 years, China's cold-formed steel production has made great progress.

The yield stress of the plate is the main factor that affects the three kinds of bending stress. The initial thickness of the plate is the secondary factor that affects the maximum radial stress and has little effect on the maximum value of the circumferential and axial stress. The radius of curvature of the inner circle is also a secondary factor that affects the maximum radial stress and has little effect on the maximum value of the circumferential and axial stresses. It can be seen from the figure that when the material yield limit increases, the maximum bending stress (absolute value) increases.
