A general velocity field for shape rolling of a V-sectioned sheet

A general kinematically admissible velocity field has been proposed in this work in examine the plastic deformation behavior of the sheet at the roll gap during shape rolling of a V-sectional sheet. This velocity field is emp loyed to examine the geometry of the rolled product, which are effected by various rolling conditions such as the sized of the raw sheet and the vacan cy, thickness reduction, etc. Furthermore, experiments on cold shape rollin g of aluminum sheet have also been conducted. The rolling forces and the sh ape of the rolled product were measured to compare with the analytical valu es. Through the comparisons between them, the validity of this newly propos ed velocity field was verified.
