  1. 1. Growth of fatigue cracks subjected to non-proportional Mode I and II

    Author : Peter Dahlin; Mårten Olsson; Veronique École; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue crack growth; Mode II overloading; Crack closure; Sequential mixed mode loading; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This thesis deals with some aspects of crack growth in the presence of cyclic loading, i.e. fatigue. The cyclic load cases studied here are primary of non-proportional mixed mode type. READ MORE

  2. 2. Crack growth in single crystal gas turbine blade alloys under service-like conditions

    Author : Frans Palmert; Johan Moverare; David Gustafsson; Mikael Segersäll; Philippa A.S. Reed; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single crystal superalloy; TMF; Crack growth; Crystallographic crack growth; Aging; Hold time; Creep crack growth;

    Abstract : This work concerns the fatigue crack growth behaviour of nickel base single crystal superalloys. The main industrial application of this class of materials is in gas turbine blades, where the ability to withstand severe mechanical loading in combination with high temperatures is required.

  4. 4. Effect of Physical Activity on Bone, Muscle and Fracture Risk during Growth

    Author : Bjarne Löfgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMC; bone size; children; exercise; fracture; growth; hip stucture analysis; muscle strength; physical activity;

    Abstract : Osteoporosis and related fractures are a global health problem. Physical activity, especially during growth, has been suggested as a strategy to improve musculoskeletal health in the population. READ MORE

  5. 5. Growth Dynamics of Semiconductor Nanostructures by MOCVD

    Author : Kai Fu; Ying Fu; Lars-Erik Wernersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Growth dynamics; Monte Carlo; semiconductor quantum dot; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Semiconductors and related low-dimensional nanostructures are extremely important in the modern world. They have been extensively studied and applied in industry/military areas such as ultraviolet optoelectronics, light emitting diodes, quantum-dot photodetectors and lasers. READ MORE
