  2. 1. Refining the fatigue assessment procedure of existing steel bridges

    Author : John Leander; Raid Karoumi; Bert Norlin; John D. Sørensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Steel bridges; Assessment; Reliability; Monitoring; Utmattning; stålbroar; bärighetsberäkning; tillförlitlighet; mätningar; Söderström; getingmidjan;

    Abstract : This thesis treats the fatigue assessment process of steel bridges. The purpose is to identify areas with potential of enhancement with an overall aim of attaining a longer service life. The aging bridge stock in Sweden and in many other developed countries is an impending economical burden. READ MORE

  4. 2. Applied Machine Learning in Steel Process Engineering : Using Supervised Machine Learning Models to Predict the Electrical Energy Consumption of Electric Arc Furnaces

    Author : Leo Carlsson; Pär Jönsson; Peter Samuelsson; Mikael Vejdemo-Johansson; Henrik Saxen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electric Arc Furnace; Electrical Energy Consumption; Statistical Modelling; Machine Learning; Interpretable Machine Learning; Predictive Modelling; Industry 4.0; Ljusbågsugn; Elenergiförbrukning; Statistisk Modellering; Maskininlärning; Tolkningsbar Maskininlärning; Prediktiv Modellering; Industri 4.0; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The steel industry is in constant need of improving its production processes. This is partly due to increasing competition and partly due to environmental concerns. One commonly used method for improving these processes is through the act of modeling. READ MORE

  5. 3. Interaction between High-velocity Penetrators and Moving Armour Components

    Author : Ewa Lidén; Bengt Lundberg; Hevré Couque; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Abstract : This work was aimed at understanding mechanisms of importance for the design of weight-efficient armour against long-rod projectiles (LRP) and shaped charge (SC) warheads. The focus was on how to achieve effective mechanical disturbances on the threat before it hits the target. READ MORE

  6. 4. Simplified dynamic analysis of railway bridges under high-speed trains

    Author : Christoffer Johansson; Costin Pacoste; Raid Karoumi; Jose M Goicolea; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic; Railway bridge; High-speed train; Moving load; Multi-span beam; Probabilistic;

    Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE

  7. 5. Patch loading resistance of plated girders : ultimate and serviceability limit state

    Author : Jonas Gozzi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : Patch loading or partial edge loading of steel girder webs is a load case where a concentrated force is introduced perpendicular to the flange of a girder. This usually induces a local failure of the girder web in the vicinity of the loaded flange. READ MORE
