  2. 1. Modelling and analysis of hydropower generator rotors

    Author : Rolf Gustavsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : In almost all production of electricity the rotating machines serves as an important part of the energy transformation system. In hydropower units, a hydraulic turbine connected to a generator converts the potential energy stored in the water reservoir into electrical energy in the generator. READ MORE

  4. 2. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

    Author : Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element modelling; alternative load paths; cross laminated timber; progressive collapse; CT scanning; fibre reconstruction; image analysis; Träteknik; Wood Science and Engineering;

    Abstract : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. READ MORE

  6. 4. Finite Element Analysis of Sheet Metal Assemblies : Prediction of Product Performance Considering the Manufacturing Process

    Author : Alexander Govik; Larsgunnar Nilsson; Ramin Moshfegh; Mats Oldenburg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis concerns the development of methodologies to be used to simulate complete manufacturing chains of sheet components and the study of how different mechanical properties propagate and influence succeeding component performance.Since sheet metal assemblies are a major constituent of a wide range of products it is vital to develop methodologies that enable detailed evaluation of assembly designs and manufacturing processes.

  7. 5. The effect of stress state in ductile failure

    Author : Imad Barsoum; Jonas Faleskog; Viggo Tvergaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile failure; Rupture mechanisms; Stress triaxiality; Lode parameter; Finite element analysis; Experiments; Localization; Micromechanics; Void growth; Void coalescence; Engineering mechanics; Teknisk mekanik;

    Abstract : The industrial application of high strength steels in structural components has increased the demand on understanding the ductile failure behavior of this type of materials. In practical situations the loading experienced on components made out of these materials can be very complex, which may affect the failure behavior. READ MORE
