Perhaps the (admittedly arbitrary) definition of plasticity could be included in this figure? I'll need to double-check, but I think it begins at the intersection with a line parallel to the elastic curve & displaced by 5%, but maybe that figure is 0.5%.--Polyparadigm 04:49, 11 Apr 2005 (UTC)

I agree, it seems like plasticity should start later in the curve -- Bavetta
