2. 11. Mechanics of Nanocellulose Foams : Experimental and Numerical Studies

   Author : Prashanth Srinivasa; Artem Kulachenko; Laurent Orgéas; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika områden, inklusive områden där dess mekaniska egenskaper är viktiga. READ MORE

4. 12. Numerical experiments - a research method in fire science

   Author : Nils Johansson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

   Abstract : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. READ MORE

5. 13. Foam-formed Fiber Networks: Manufacturing, Characterization, and Numerical Modeling : With a Note on the Orientation Behavior of Rod-like Particles in Newtonian Fluids

   Author : Majid Alimadadi; Per Gradin; Pär Jonsén; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D fiber network structure; foam forming; numerical modeling; compression simulation; orientation; wall-bounded flow; CFD; Jeffery orbits; LS-DYNA;

   Abstract : Fiber networks are ubiquitous and are seen in both industrial materials (paper and nonwovens) and biological materials (plant cells and animal tissues). Nature intricately manipulates these network structures by varying their density, aggregation, and fiber orientation to create a variety of functionalities. READ MORE

6. 14. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters

   Author : Shun-Han Yang; Chalmers tekniska högskola; []

   Abstract : To reduce greenhouse gas emissions and expand the energy mix, there is a pressing need for the exploitation of renewable sources of energy, such as biomass, hydropower, solar power, waves, and wind. This thesis focuses on ocean wave energy and its applications. READ MORE

7. 15. Analysis and numerical methods for multiscale problems in magnetization dynamics

   Author : Lena Leitenmaier; Olof Runborg; Carlos Garcia-Cervera; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

   Abstract : This thesis investigates a multiscale version of the Landau-Lifshitz equation and how to solve it using the framework of Heterogeneous Multiscale Methods (HMM). The Landau-Lifshitz equation is the governing equation in micromagnetics, modeling magnetization dynamics. READ MORE
