Ultrasonic roll bite measurements in cold rolling – Roll stress and deformation [PDF]
Journal of Materials Processing Technology, 2017 In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity. To control the process, several online measurements are usually carried out such as the rolling load ...

Change of the yield stress in roll formed ERW pipes considering the Bauschinger effect [PDF]
Journal of Materials Processing Technology, 2017 ERW pipes formed with the roll forming process show a yield stress distribution along the circumferential direction and their quality is strongly influenced by the magnitude and by the distributions of the yield stress.

Evolution of Residual Stress Based on Curvature Coupling in Multi-Roll Levelling
Applied Sciences, 2019 Residual stress is the main cause of flatness defects in sheet metal and the basic method to improve the shape quality of the sheet is to reduce and eliminate the residual stress by multi-roll levelling.

Review of wound roll stress in roll-to-roll manufacturing of flexible electronics [PDF]
Chinese Science Bulletin, 2019 Flexible electronics has been widely used in many main-stream applications like flexible display, thin-film solar cell, RFID tags, flexible sensors, and so on. Roll-to-roll (R2R) is a kind of method by which flexible substrate can be processed in a continuous way.
