1. Rate-dependent effects on the mechanical behaviour of paper
Master-uppsats, KTH/HållfasthetsläraSammanfattning : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. LÄS MER
2. The “threat from abroad” and the breaking of the Swedish “cordon sanitaire” : A critical discourse analysis of right-wing party-political, online communication in Sweden
Master-uppsats, Uppsala universitet/Medier och kommunikationSammanfattning : In the last decade, we have witnessed a new stage in the mainstreaming and normalization process of populist radical right policies and ideas in the Western world. This has resulted in increasing politicization of issues related to immigration. LÄS MER
3. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

4. Fuktbetingade rörelser i tak : Veckbildning i tätskikt på tak av trä
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : Veckbildning i bitumenbaserade tätskiktmattor är ett problem som är känt i branschen. Problemet uppstår oftast på underlagstak av trä som är byggda under årets fuktigaste period, oktober-november, och vecken börjar då att bildas i slutet av våren i takt med den ökande solinstrålningen.

5. Continuum damage modeling of delamination in paperboard
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraSammanfattning : 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. LÄS MER
