DUAL-TEN^® Brochure - Forming Limits

As shown in Figure 5, the ASM standard shape of the forming limit curve for steel can be used for DUAL-TEN^® steel, and the equation for the FLC calculation using n-value and sheet thickness is still valid for DUAL-TEN^® steel.  The n-value used for the FLC calculation should be determined from stress and strain data from 10% strain to end of uniform elongation.
