How Do You Calculate Roller Separation for Elastic Recovery in Rolling Mills?

[Snoopdork]

No idea where to start with this one, any help is much appreciated...

"A metal plate needs to be reduced to a thickness of 4 cm by involving a rolling mill. After rolling, the elastic properties of the material cause the plate to regain some thickness. Calculate the needed separation between the two rollers when the yield strength of the material after plastic deformation is 60MPa and modulus of elasticity is 124GPa."

Calcuate the elastic strain from the yield stength and elastic modulus.

Then calculate the amount of elastic deformation (recovery) in 4 cm. The separation has to be less than final thickness because the elastic deformation is recovered.

Great, thank you.
