4. Cold-formed faults – Main features
4.1 Impact of the forming operation
4.1.1 On mechanical characteristics
Regardless of the cold forming method used, the mechanical properties of the material are altered.
When a profile is cold-formed from sheet metal or strip, the roll-forming operations result in work-hardening of the bending zones, leading to an increase in the yield strength of the initial product and, to a lesser extent, its tensile strength, located in the vicinity of these bending zones.
