...Feng Zhang; Arif S. Malik In thin-gauge cold rolling of metal sheet, the surface roughness of work rolls (WRs) is known to affect the rolled sheet surface morphology, the required rolling load, and the roll wear. While modeling of rough surfaces using statistical asperity theory has been widely...

...Peng Cheng; Y. Lawrence Yao Cold-rolled sheet metal that is often used in laser forming exhibits anisotropic properties, which are mostly caused by preferred orientations of grains developed during the severe plastic deformation such as cold rolling. In the present study, the textures of cold...

...S. Ghosh, Professor,; M. Li; D. Gardiner, Post Doctoral Fellow This paper identifies various modeling issues that are necessary for successful simulation of the cold rolling process by comparing it with experiments on aluminum alloys. It combines considerable experimental studies with finite...

... cold rolling mechanical stability nonlinear dynamical systems During the cold rolling of thin metal sheets, undesired mechanical vibration commonly known as chatter is often observed. Chatter could lead to unacceptable gauge fluctuations (often as much as 50 percent), striations on the rolled...
