Shifting a forming limit curve based on zero friction analysis

A method for improving a hemispherical dome test includes calculating a forming limit diagram (FLD) based on a plurality of simulated data associated with a sheet metal transformation technique. The method also includes performing zero friction analysis on the sheet metal transformation technique. T...
