  1. 1. Patch loading : resistance of steel girders subjected to concentrated forces

    Författare :Ove Lagerqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Different aspects concerning the resistance of steel girders subjected to concentrated forces have interested a large amount of researchers all over the world. The subject most dealt with among researchers is what is called "patch loading", a concentrated force applied at one flange. LÄS MER

  3. 2. Patch loading : resistance of longitudinally stiffened steel girder webs

    Författare :Carlos Graciano; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : In most cases, longitudinal stiffeners increase the resistance of steel girder webs subjected to concentrated forces, commonly referred to as patch loading. During the last three decades, a number of experimental investigations have been undertaken in all over the world in this regard. LÄS MER

  4. 3. Transverse cracking in cross-ply composites during static and fatigue loading at different temperatures

    Författare :Vivek Richards Pakkam Gabriel; Patrik Fernberg; Mohamed Sahbi Loukil; Kristofer Gamstedt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer composite laminate; Static loading; Fatigue loading; Elevated temperature effect; Weibull distribution model; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : Polymer composite laminates are preferred in many load bearing applications for its tailorable mechanical properties while offering light-weight solution, corrosive resistance etc. Hence, polymer composites are attractive material choice for aircraft manufacturers to reduce weight and emissions.

  5. 4. Development of a Methodology for Dynamic Testing of Rock Support : Field Tests and Numerical Analysis

    Författare :Shahin Shirzadegan; Erling Nordlund; Ping Zhang; Charlie Chunlin Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The increasing mining depth in the Luossavaara-Kiirunavaara Aktiebolag (LKAB) mine located in the northern part of Sweden leads to higher stress magnitudes, resulting in increased seismic activity and more seismically-induced damage. The effectiveness of various ground support systems under dynamic loading conditions has therefore become of prime interest to LKAB for successful and safe mining at deep levels. LÄS MER

  7. 5. Evaluation of Shoulder-Complex Motion in Frontal and Oblique Impact Loadings - A Comparison between Frontal Impact Dummies and the Human Body

    Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sled tests; Cadaver; Volunteers; Kinematics; Hybrid III; Static loading; Shoulder range-of-motion; Offset frontal collision; THOR; Shoulder; Biofidelity; Oblique frontal collision; Crash test dummy; Post Mortem Human Subjects PMHS ;

    Sammanfattning : Offset and angled frontal impacts represent a crash type that is more common than full-frontal collisions. Several studies have shown that over 70% of all frontal impacts are offset or oblique. LÄS MER
