Abstract
The aim of this thesis is to investigate the micro mechanical damage and the failure of
paperboard during sharp edge cutting. Tetra Pak is at the very forefront of the food
packaging industry and in order to keep this market position, continuous improvements
are of great importance. Increased understanding of paperboard behaviour is a driving
factor for these improvements, since it enables more accurate simulations and further
on manufacturing optimisations.

This thesis is divided into two parts: Experimental testing and finite element modelling.
The experiments are thoroughly evaluated by using tomography, microscopy and
statistical analysis. The interesting observations made during the experiments are all
clarified. Several... (More)
The aim of this thesis is to investigate the micro mechanical damage and the failure of

This thesis is divided into two parts: Experimental testing and finite element modelling.
The experiments are thoroughly evaluated by using tomography, microscopy and
statistical analysis. The interesting observations made during the experiments are all
clarified. Several possible modelling approaches are theoretically reviewed and a final
finite element model using element deletion is implemented.

The physical reasoning about the cutting phenomenon, based on the experiments,
contributes to an increased understanding of which parameters that affect the cutting
and also the understanding of the virtual responses. The results from the finite element
modelling captures the observations and responses.

This thesis constitutes a foundation from which further development should be based.
Future work should include development of the testing procedure as well as the
implemented finite element model. (Less)
Popular Abstract
Tetra Pak is always pursuing understanding of what is really happening in their processes and by accurately simulating
manufacturing scenarios, Tetra Pak can gain increased knowledge in a cheap and time efficient way. It is now high time to understand
what really happens when paperboard is cut and try to capture this virtually.
