    • The aged state has a density about 0.5% lower than rejuvenated states. The volume change under compression is typically smaller than this. Larger changes are seen under extension, but they only exceed 3% for strains bigger than 0.8. These small changes would have little affect on the plots shown. It is also worth noting that, like stress and orientation, the volume of deformed systems is independent of strain history
