1. 11. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Wickramasooriyage Devmini Kularatne; [2022]
   Nyckelord :Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

   Sammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER

3. 12. FEM Analysis of paperboard packaging

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Wen-Che Li; [2022]
   Nyckelord :;

   Sammanfattning : The work aims to provide a finite element model using Ansys Workbench for realistically simulating paperboard packages. The geometrical properties of a package and the loading conditions were altered to investigate their influence on the box behavior and the applicability of Ansys as the finite element solver for paperboard material.

4. 13. The supporting structures of entrepreneurship - a case study on the entrepreneurial development in a rural community

   C-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

   Författare :Edward Cornell; Hanna Hedlund; [2022]
   Nyckelord :entrepreneurship; culture; network theory; socio-economics; rural communities;

   Sammanfattning : In the last centuries, Sweden's rural communities have experienced a constant decreasing population to pave the way for the urbanization trend. Studies have found that innovation is a driver for a city's survival and thriving, but still, rural communities have experienced a deteriorated attitude towards entrepreneurship. LÄS MER

5. 14. Adhesive bonding of fiber laminate patch to sandwich-structured composite

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Daniel Nesic; [2022]
   Nyckelord :Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

   Sammanfattning : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. LÄS MER

7. 15. Fatigue Life Prediction of a Topology-Optimised Polyamide-12 Part Manufactured with Multi-Jet Fusion Technology

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik
