Abstract
In the present study, two different yield criteria were investigated to model and compare
the yield thresholds functions for the plastic behavior of rolled sheets. These two different yield
criteria as described via Hill48 yield quadratic and F. Barlat Yld2000-2d non-quadratic criterion.
For this purpose, an experimental device of simple tensile test and the studied material are
described. The experimental results in terms of Yield stress and Anisotropic coefficient are
estimated from the Associated Flow Rule (AFR) and Non-Associated Flow Rule (NAFR).
However, it is found that the criterion of Yld2000-2d is the most appropriate model in comparison
with the experimental results.
