Numerical and experimental investigation of hole flangeability of AA6061 alloy

Abstract Hole flangeability is a measure of edge formability or local formability, and it important for forming processes like stretch flanging. sheet metals evaluated by determination hole expansion ratio (HER) using standard test (HET). In the present work, numerical experimental investigation has been carried out on 1.6mm thick AA6061 alloy sheets. The material model plays an role in accuracy predicted results simulations. simulations have two different work hardening laws (Swift Voce). failure experimentally determined limit curve (FLC) HER thickness along expanded simulation. thinning from FE simulation validated performing tests according to ISO 16630-2009 conical punch. found be good agreement with results.
