3D Cantilever Model Research on Roller Leveling Process of Plate with Lateral Buckling Defects

Abstract:

Roller leveling of plate with lateral defects is a complex process in which materials longitudinal strain couples with the transverse one. Different from wavy defects, lateral buckling defects are plates' macroscopic deformation because of stress or fiber length difference between up and down surfaces of the plate. Aiming at plate roller leveling process,a simplified 3D cantilever bending FEM model has been suggested in this paper. In the model, plates longitudinal bending and lateral warping are decoupled by using ABAQUS element deactivation function. Moreover, the mechanism of roller leveling process for plates with lateral buckling defects has been developed. On the basis of comparing with the ideal flat plates' bending process, effects of technological parameters such as reduction, roller diameter and roller shape on the lateral buckling defects correction during roller leveling process are also studied.
