These are all PDF documents and contain the information you seek.

From what I can gather based upon what I have read. The influence of a neutral plane has to do with the slippage of a metal during the rolling process, of course the PDF documents are much more informative.

Answer 2

the neutral plane in rolling metal is the center of the thickness of the metal form, like, plate,flat bar, round bar etc.
When rolling, the inside shrinks, the outside stretches and the center line remains the same.
If you measure the circumference after rolling you will see the difference between the finished piece and the piece before rolling.
This is also called the neutral diameter.
