Numerical simulations of sheet metal forming processes need the establishment of highly reliable results, which in turn need the accurate identification of mechanical properties. In this paper a study is presented on the choice of the characterization function of flow stress-strain curve of sheet metal materials, as well as the selection of the best yield locus, based on experimental uniaxial t...

Norm-referenced testing is integral to the practice of psychological and educational testing. Originated in the work of modern statistics, this assessment method assumes that human traits and characteristics, such as intelligence, academic achievement, and behavior, are distributed along a normal probability or bell-shaped curve (hereafter, referred to as the normal curve). The normal curve rep...
