Experimental setup for studying the behavior of sheet blanks during cyclic alternating bending for roller levelling application
Roller levelling is a technological process of metal forming, used to minimize the flatness of sheet blanks and reduce the level of residual stresses. When levelling, the workpiece is subjected to cyclic alternating bending with decreasing amplitude. The report presents an experimental testing set-up designed and used to determine the mechanical response of sheet steel blanks under different loading modes. The equipment is described and the first results are presented.
