This study concerns on the plastic behaviour of (Al-2%Cu) sheets undersimple tension, plane strain tension and balanced biaxial tension. Experimentalyield loci were extracted based on the constant strain energy theory, comparisonswith the proposed two yield criterion after R. Hill , showed that the experimentalyield loci does not follow very well the old yield criterion, but it can be fitted betterwith the new yield criterion. The determined value of ''M'' in the new yieldcriterion were ( m = 1.85 ).
