Boundary Element Method in Predicting Roll Deformation in Cold Rolling — Toward A Library of CAD/CAM Programmes

  • A. M. A. Mansour


Hitchcock’s formula is usually used to predict the roll radius in cold rolling theories. For a CAD/CAM package, this approach is not appropriate. In this work a small BASIC computer programme based on the simplest type of Indirect Boundary Elements is employed. The programme is shown to be fast and capable of predicting the displacement and the inconstant radius of the roll in the contact zone. It is shown that this computer code can be incorporated in a CAD/CAM package more easily than a Finite Element program. The need to use such a package is demonstrated by presenting the roll deformation for standard load cases, and showing the differences with Hitchcock’s formula.
