Major strain distribution for a sheet metal blank during a Nakajima cupping test for determination of forming limit curve.

During a bulge test, a sheet metal blank is pressured with oil until it fails. ARAMIS records the oil pressure in order to calculate the biaxial flow curve (stress-strain evaluation) and thickness reduction distribution. The biaxial flow curve is a material parameter used as input in forming simulations (FEA).
