Polymer is flexible lightweight materials and can be produced into thin films at a low cost.
Furthermore, the nano ZnO/PMMA composites have potential applications in UV protecting sheets and films, transparent barrier or protective layers, antireflection coatings and as materials with increase thermal stability [11].

Leveler has been an indispensable part of the rolling plant, and its application spreads broadly to some plants whose incoming materials mostly compose of sheets, such as automobile factory, shipyard and so on.
So it is correct to choose stronger material as U71Mn whose material parameters’ value will be given as follows: failure stress σS=550MPa; strain deformation rate n=0.8; constant of rate β=0.8; modulus of elasticity E=210,000MPa.

Being valid only for a specific value of yield strain (E/σo=0.002) implies that their formula are far from practical use, since yield strain of real materials naturally varies over a wide range.
