This paper describes about the intensity of stress concentration, and the maximum stress component occurred on the inside liner of a corrugated fiberboard during a rotary creasing process. Three dimensional finite-element analysis, based on the combination of orthotropic-elastic liners and Ring Crush Test based medium, was carried out by varying mechanical conditions such as the working diameter of the main-creaser, the boundary constraint of lateral tensile state and the misalignment of the biting position with an apex of corrugated medium. The simulated stress distribution and deformation shape of inside liner explained about a few experimental features, such as the failure occurrences on the inside liner.
