1. Residual stresses in paperboard and the influence of drying conditions
Sammanfattning : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. LÄS MER
2. Modelling Fiber Network Materials:Micromechanics, Constitutive Behaviour and AI
Sammanfattning : This thesis focuses on understanding the mechanical behavior of fiber-based materials by utilizing various modeling approaches. Particular emphasis is placed on their structural variability, anisotropic properties, and damage behavior. LÄS MER
3. Micromechanics of Fiber Networks
Sammanfattning : The current trends in papermaking involve, but are not limited to, maintaining the dry strength of paper material at a reduced cost. Since any small changes in the process affect several factors at once, it is difficult to relate the exact impact of these changes promptly. LÄS MER
4. Insights in paper and paperboard performance by fiber network micromechanics
Sammanfattning : Fiber networks are ubiquitous due to their low cost and high ratio of mechanical performance to weight. Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (board). Often the ideal product is both mechanically sturdy and possible to print on.

5. Micro-mechanical characterization and modeling of paper and paperboard
Sammanfattning : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.
