  2. 16. Transitional and turbulent fibre suspension flows

    Author : Mathias Kvick; Fredrik Lundell; Daniel Söderberg; Lisa Prahl Wittberg; Björn Hof; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; fibre suspension; turbulence; laminar-turbulent transition; image analysis; hydrodynamic stability; cellulose nanofibrils.; Engineering Mechanics; Teknisk mekanik;

    Abstract : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. READ MORE

  4. 17. A Fracture Mechanics Approach to Study Hydrogen Embrittlement in High Strength Martensitic Steels

    Author : Armin E. Halilović; Pål Efsing; Jonas Faleskog; Carl F.O. Dahlberg; Covadonga Betegon; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : High strength steels that are subjected to hydrogen experience embrittlement where the mechanical properties are reduced, and premature failure of components may occur. Although the phenomenon has been recognized for over 150 years, it is not clear what drives embrittlement. READ MORE

  5. 18. On fiber network fracture mechanics and kink band formation in biocomposites

    Author : Vedad Tojaga; Sören Östlund; Artem Kulachenko; T. Christian Gasser; Emanuela Bosco; KTH; []

  6. 19. Electronic speckle photography applied to in-plane deformation and strain field measurements

    Author : Mikael Sjödahl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Non-contacting measurements of deformation and strain fields are of great importance in experimental mechanics. This thesis describes the development and applications of a video-based, computerized system called electronic speckle photography that measures the in-plane deformation of a strained body.

  7. 20. A pulsed TV holography system for the study of transients in experimental mechanics

    Author : Per Gren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : An all-electronic system for pulsed holographic interferometry called pulsed TV holography is developed. This is a whole-field non-contacting optical measurement method suitable for studies of transient events like wave propagation in solids and fluids. READ MORE
