This paper relates the cold forming of the alloy 2117-T4 and the description of a constitutive model for low temperatures and plastic strain rates. The characterization of the alloy was done by cylinder upsetting aided by a finite element code (FORGE2®) and following an inverse approach. Taking into account the assumptions associated to the software, the parameters of the Hansel-Spittel and hyperboloid-type models were identified assuming a von Mises material.
