Hello,
Is using Poisson's ratio to calculate the cross sectional area accurate after a material has been extensively cold worked and deformed. For example say I have a wire at some nominal length and thickness (which is too small for me to precisely measure, but I know at the start). So can I calculate the cross sectional area from the initial values say after I cold work the wire and get a 20% increase in length, using Poisson's ratio, or perhaps a calculation based on a constant volume assumption. Or is it impossible to calculate it fairly accurately either way?
Thanks,
-Scott
