Abstract
Systems and methods of deriving peak fracture strain values of a metal experiencing fracture failure from measured data obtained in a specimen test are disclosed. Metal fracture failure criteria, a measurement characteristic length in a specimen test and characteristics of a neck formed in the metal are received in a computer system. The metal fracture failure criteria contain respective measured critical strain value and average fracture strain value in various loading conditions. The characteristics of the neck include the neck's width and a profile of strain distribution within the neck's width. Respective peak fracture strain values are calculated for various loading conditions using a formula based on the profile of strain distribution, the neck's width, and measured critical strain value and average fracture strain value. Peak fracture strain values can be used in a numerical simulation of sheet metal deformation for more accurately predicting structural behaviors of metal.
