Plastic Deformation

· The diagram shows the format of a rolling mill in which small diameter rolls have been used to decrease the required driving torque.
· To make the elastic performance of the small diameter rolls acceptable (i.e. no bending) they must be supported by larger diameter rolls.

From: Kalpakjian, "Manufacturing Processes for Engineering Materials," Addison Wesley (1991)

· The system shown has a cascade of such support rolls to permit the required loads to be applied.
