  2. 1. Design of steel piles for integral abutment bridges

    Author : Hans Petursson; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integral abutment bridges; steel piles; jointless bridges; Steel Structures; Stålbyggnad;

    Abstract : In 1999 research was started at Luleå University of Technology with the purpose to collect experiences from USA and UK on bridges with integral abutments and transfer the experience to Swedish conditions. Since then at least 20 integral bridges with one row of piles under each abutment have been built in Sweden and the European research project INTAB has been completed. READ MORE

  4. 2. A Comparative Investigation of Gear Performance BetweenWrought and Sintered Powder Metallurgical Steel : Utilizing In-situ Surface Profile Measurements to Investigate theInitiation and Evolution of Micropitting and Pitting Damage

    Author : Edwin Bergstedt; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear testing; Micropitting; Pitting; Efficiency; Surface transformation; Kugghjulstestning; Micropitting; Pitting; Effektivitetsmätning; Yttransformationer; Machine Design; Maskinkonstruktion;

    Abstract : Vehicle electrification is a strong trend that introduces new challenges, such as increased input speed of the transmission and increased power density. Alsothe noise emittance of the gearbox is of increasing importance, as the sound of the gearbox is no longer masked by the internal combustion engine. READ MORE

  5. 3. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Author : Daniel Wiklund; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel sheet; tribology; surface topography; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  6. 4. Plastic design of steel bridge girders

    Author : Frank Axhag; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis assesses the feasibility of a modified plastic design method for continuous steel or composite bridges with slender I-girders. The feasibility evaluation of the design method is closely connected to the moment-rotation relationship of the I-girders at internal supports. READ MORE

  7. 5. Stainless steel box columns in fire : analysis and design recommendations

    Author : Björn Uppfeldt; Olivier Vassart; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : The use of stainless steel in buildings is small but increasing, mainly due to the low maintenance costs, favourable corrosion resistance and aesthetic appearance. It is well known that stainless steel also performs better than carbon steel at elevated temperatures. READ MORE
