  • Shifting a forming limit curve based on zero friction analysis
    Patent number: 11886778
    Abstract: 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. The method also includes shifting the FLD based on the zero friction analysis.
