Can edge quality impact the validity of a forming limit diagram?

September 17, 2020

Both material type and thickness can affect formability modeling, which is based, in part, on forming limit diagrams(FLDs). When the EWI forming lab experienced edge cracking and distortion with thin, nickel-based super alloy, it decided to test the material against the ISO standard for FLDs. Would the standard hold up?

EWI Applications Engineer Laura Zoller has written about the study and its results in Effects of Edge Quality in Creating Reliable Forming Limit Diagrams.
