  2. 21. Application of Fracture Mechanics to Concrete Bridges. Finite element analyses and experiments

    Author : Mario Plos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; reinforcement splice; full-scale test; shear failure; fracture mechanics; fatigue test; static test; concrete frame corner; non-linear finite element analysis; concrete bridge;

    Abstract : Material models based on fracture mechanics together with non-linear finite element analyses have been used in combination with experiments to study the behaviour of reinforced concrete bridges. The work covers two aspects of interest in the design of concrete bridges.* The shear behaviour was studied in full-scale tests on two highway bridges. READ MORE

  4. 22. Ductile failure and rupture mechanisms in combined tension and shear

    Author : Imad Barsoum; Jonas Faleskog; Björn Skallerud; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This licentiate thesis is generally concerned with the ductile failure and rupture mechanisms encountered under combined tension and torsion loading. In the first part entitled Paper A, an experimental investigation of the rupture mechanisms in a mid-strength and a high strength steel was conducted employing a novel test configuration. READ MORE

  5. 23. Energy Absorbing Material Concepts for Automotive Accident Injury Prevention

    Author : Rickard Juntikka; KTH; []
    Keywords : Head impact; energy absorption; cellular materials; automotive; dynamic; pedestrian; interior; compression; shear; finite element analysis; optimisation;

    Abstract : Although automotive safety has experienced a rapiddevelopment during the last decades, traffic related accidentsrank very high in many countries in terms of cause of death.Statistics show that the head is the body region mostfrequently injured in motor vehicle accidents and the primarycause of death is head injuries.

  6. 24. Modelling of Forming and Welding in Alloy 718

    Author : Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; welding; Alloy 718; damage; GISSMO; failure; Hållfasthetslära; Solid Mechanics;

    Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. READ MORE

  7. 25. Bridge Overhang Slabs with Edge Beams : LCCA and Structural Analysis for the Development of New Concepts

    Author : José Javier Veganzones Muñoz; Costin Pacoste; Raid Karoumi; Lars Pettersson; Rui Vaz Rodrigues; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Overhang slab; Edge beam; Life-cycle Cost Analysis; Non-linear FE-analysis; Design methods; Shear force; Failure mode; Effective width; Minimal width.; Konsolplattor; Kantbalkar; Livscykelkostnadsanalys; Icke-linjär FE-analys; Dimensioneringsmetoder; Tvärkrafter; Brott; Fördelningsbredd; Minimal bredd.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Bridge edge beams are associated with high life-cycle costs because of the need of maintenance, which also causes traffic disturbances. For this reason, the Swedish Transport Administration started a project to find better solutions. One of the proposals was a design without edge beam. READ MORE
