1. 11. Experiments and Modelling of Composite–Aluminium Bolted Joints

   Författare :Hannes Wemming; Zlatan Kapidžić; Stefan B Lindström; Lars Johansson; Stefan Hallström; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The aeronautical industry has always strived towards weight-efficient structures since they improve aircraft performance, enable more fuel or payload, reduce cost of manufacturing and operating the aircraft, and reduce the fuel consumption and emissions. Modern airframes are often built in materials with high strength-toweight and stiffness-to-weight ratio, such as aluminium or fibre composites. LÄS MER

3. 12. Wood shrinkage in CT-scanning analysis

   Författare :José Couceiro; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

   Sammanfattning : Computed tomography (CT) can be used to study wood-water interactions in differentways, such as by determining wood moisture content (MC). The determination of MCrequires two CT images: one at the unknown moisture distribution and a second one ata known reference MC level, usually oven-dry MC. The two scans are then compared. LÄS MER

4. 13. Mechanical behaviour of glassy polymers: experiments and modelling

   Författare :Jonas Engqvist; Hållfasthetslära; []
   Nyckelord :;

   Sammanfattning : This thesis presents experimental investigation and modelling of the mechanical response of glassy polycarbonate (PC) during deformation. The mechanical response is studied experimentally over a wide range of length-scales using X-ray scattering techniques and optical full-field deformation measurement by Digital Image Correlation (DIC).

5. 14. Fluid structure interactiontesting, modelling and development of Passive Adaptive Composite foils

   Författare :Laura Marimon Giovannetti; UK University of Southampton; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : High performance foiling catamarans are one of the fastest growing sectors in the sailing and sport industries, allowing athletes to perform in extremely fast and spectacular boats. These boats fly above the water with the aid of foils that not only provide horizontal side-force to counterbalance the aerodynamic forces from the sails, but also deliver vertical force that supports some or all of the mass of the boat.

7. 15. Deformability of unidirectional prepreg materials

   Författare :Ylva Larberg; Malin Åkermo; Patrik Fernberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prepreg; deformability; carbon composite; Vehicle engineering; Farkostteknik;

   Sammanfattning :  To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An automatic tape layer (ATL) can be used to perform the lay-up in an efficient way. LÄS MER
