1. Validation of An Iteration Free Material Model for Paperboard (NEO)
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE

2. Multiscale mechanical modeling of paperboard
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. READ MORE

3. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. READ MORE

4. Continuum damage modeling of delamination in paperboard
University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraAbstract : This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. READ MORE

5. FE-analysis of roller creasing of corrugated board
University essay from KTH/HållfasthetsläraAbstract : Creasing is often performed on paperboard to lower the bending stiffness in a region, making the paperboard easier to fold. Packsize AB uses rolls to crease corrugated paperboard. When using rolls for creasing double-walled corrugated paperboard in the machine direction, fracture occasionally occur on the top liner.
