1. 26. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints

   Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRP steel joints; durability; fibre reinforced polymer; cohesive zone modelling; long-term performance; adhesively bonded joints; moisture diffusion;

   Sammanfattning : Fibre reinforced polymer (FRP) composites offer excellent properties, such as high specific strength and stiffness, corrosion resistance and light weight. Over the past four decades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

3. 27. Efficient production of high-rise buildings

   Författare :Hanif Hoseini; Gudni Jóhannesson; Bertil Fredlund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

   Sammanfattning : Production of one family houses has over time developed successfully in Sweden and producers have managed to reduce the production costs and industrialize the production process. The development has however not been that successful when it comes to high-rise buildings. LÄS MER

4. 28. Microstructure Evolution and Mechanical Properties of Haynes 282

   Författare :Ceena Joseph; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

   Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER

5. 29. Social Construction of Technical Aids - Personal Meaning and Interactional Effects of Disability and Assistive Devices in Everyday Life

   Sammanfattning : This thesis concerns the role of disability and assistive devices in everyday life among persons with, for instance, impairments related to mobility (e.g. wheelchair users) and bodily shape and configuration (e.g. LÄS MER

7. 30. Computational studies of graphene and single walled carbon nanotube growth and carbonaceous polymeric nanocomposites

   Författare :Shayesteh Haghighatpanah; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; functionalization; carbon nanotube; Monte Carlo; tight binding; polyacrylonitrile; polyethylene; molecular mechanics; molecular dynamics.;

   Sammanfattning : Graphene and single walled carbon nanotube (SWNT) has attracted a lot of attention in different fields of science due to its unique electrical, mechanical, and optical properties. Controlling the growth of graphene and SWNT is a very topical subject and critical for producing material with desired properties since their properties are highly dependent on their atomic structure and it is often desirable that the material contains very few or (if possible) no defects.
