Experimental and numerical studies of creasing of paperboard [PDF]

International Journal of Solids and Structures, 2009
A laboratory creasing device to capture the most important properties of a commercial rotary creasing tool was designed. Finite element analysis of the creasing of a multiply paperboard in the laboratory crease device was presented.

Experimental and numerical investigation of creasing in corrugated paperboard

Philosophical Magazine, 2008
Creasing is a process which indents a section of corrugated board along fold lines to facilitate a neat fold. The most common failure site in a box made out of corrugated board is at the folds, where the stiffness is reduced by the creasing operation ...

THE ASSESSMENT OF CREASE-RESISTANCE AND CREASE-RECOVERY

Journal of the Textile Institute Proceedings, 1962
A description is given of a new method for the assessment of the creasing properties of fabrics. In this crease test, the fabrics are creased in a reproducible, non-random way. The creased fabrics are ranked by subjective evaluation under standardised conditions. Photographic standards may be of use in this judgement.

The Mechanics of Creasing and Crease Recovery

Textile Research Journal, 1968
The "blocking friction" model by Grosberg et al. has been applied to experimental results of loop bending recovery by Stuart et al. The failure is demonstrated and ex plained qualitatively. Then the "continuous" frictional-plasto-elastic model by Olofsson is applied together with a hypothesis of "form conservation" whose general importance is further ...
