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