  1. 11. DURABILITY STUDY OF REJUVENATED RAP BINDERS

    University essay from KTH/Kemiteknik

    Author : An Na Lay; [2022]
    Keywords : RAP reclaimed asphalt pavement ; rejuvenator; bitumen; rheology; ageing; RAP; bitumen; föryngringsmedel; reologi; åldring;

    Abstract : När priset på naturtillgångar ökar samt att industrier måste ställa om till en mer hållbar verksamhet innebär detta även en omställning för asfaltsindustrin. Ett sätt för att använda mer återvunnet material i asfaltsindustri är att använda bindemedlet från gammal asfaltsmassa (eng.: reclaimed asphalt pavement, RAP). READ MORE

  3. 12. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

    University essay from

    Author : David Barjosef; Alexander Austen Öhrn; [2022]
    Keywords : ;

    Abstract : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. READ MORE

  4. 13. Cracking and Fatigue in the Prestressed Concrete Bridge at Autio

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Kasper Andersson; Jon Leidzén; [2022]
    Keywords : Fatigue; Cracking; Prestressed Concrete Bridge; Rainflow;

    Abstract : In early 2020, cracks were discovered on the bridge crossing the Torne River at Autio. This resulted in an investigation being launched to determine the structural state of the bridge. READ MORE

  5. 14. Crack propagation in 3D-printed PLA

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Johan Stenborg; Amaro Ramirez Flores; [2022]
    Keywords : Crack; 3D printing; crack propagation; FEM; fracture; crack simulation; image correlation; Sprickor; Sprickbildning; 3D printing; spricksimulering; DIC-analys;

    Abstract : Cracks form in all materials. This project was about investigating the crackpropagation in 3D-printed PLA. Both simulations and experiments has beenperformed to get the results. The simulations used a already written code to solvethe problem with FEM. READ MORE

  6. 15. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE
