MODELING OF CURL AND TWIST IN MULTI-PLY PAPERBOARD

摘要

This paper describes a grey-box model for the dimensional stability properties (i.e. curl) of the carton board produced at AssiDomaen Froevi, Sweden. The main equations are based on classical lamination theory of composite materials, and each constituent ply is considered as a macroscopic homogeneous, elastic medium. The model shows a general agreement between predicted and measured curvatures.
