1. 16. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

   Författare :Karin Yvell; Annika Borgenstam; Peter Hedström; Göran Engberg; Johan Moverare; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

   Sammanfattning : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. LÄS MER

3. 17. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

   Författare :Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. LÄS MER

4. 18. Load Bearing Capacity and Behaviour of Composite Slabs with Profiled Steel Sheet

   Författare :Li An; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load bearing capacity; composite slabs; shear resistance; concrete;

   Sammanfattning : In many cases the capacity of composite slabs with profiled steel sheeting depends on the shear resistance at the sheet-concrete interface. This shear resistance is essential to the interaction between the steel sheeting and the concrete. Besides this, other factors also affect the behaviour of composite slabs. LÄS MER

5. 19. µPIV Measurement of Grease Velocity Profiles

   Författare :Jinxia Li; Henrik Åström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : Lubricating grease is commonly applied to lubricate e.g. rolling bearings, seals and gears. Grease has some clear advantages over lubricating oil. LÄS MER

7. 20. Behaviour of pretensioned bolts in friction connections : towards the use of higher strength steels in wind towers

   Författare :Christine Heistermann; Carlos Rebelo; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

   Sammanfattning : During recent years wind energy has established as an alternative to commonenergy sources. To advance its competitiveness, the costs for the constructionof a wind tower have to be reduced. One possible option is the use of frictiongrip joints instead of flange connections to join various tower segments in atubular steel tower. LÄS MER
