Abstract
Previous research about mechanical properties in shear of paperboard is limited. The out-of-plane properties of paper have been investigated in this work.
To mimic the industrial processes of packaging paperboard, shear tests have been performed. Compression has also been applied in the ZD-direction to mimic the high shear from the creasing.
The mechanical behavior of paperboard in the MD- and CD are similar and can be regarded as equal.
There seems to be a small size effect where smaller samples yield different mechanical properties compared to bigger samples sizes.
In this study, simple shear under climate-controlled environment has been studied but the measurements showed little difference in mechanical properties when the... (More)

In this study, simple shear under climate-controlled environment has been studied but the measurements showed little difference in mechanical properties when the relative humidity was slightly increased.
Simulating the experiments required a stiff cohesive zone to allow the desired separation, although the FE-simulations in ABAQUS were close to the performed experiments the used cohesive zones did eliminate some of the observed experimental behavior, suggesting that a cohesive approach in paperboard is complex.

Popular Abstract
Paperboard is complex to model due to high anisotropy, non-linear elasticity and sensitiveness to moisture content in the material.
Delamination between layers occurs when paperboard deforms plastically which makes that paperboard can not be only modeled as continuum. The knowledge about the out-of-plane mechanical properties is limited due to the limited research.
It was found that the difference between the MD- and CD-direction in paperboard is minor and could be neglected.
