1. 1. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

   Detta är en avhandling från Chalmers University of Technology

   Författare :Anders Kullingsjö; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Case history; Constitutive models; Deep excavation; Earth pressure; Finite element method; Ground surface settlement; Retaining wall; Sheet pile wall; Soft Clay; Soil-structure interaction; e-ADP; MIT-S1; Analysis; Anisotropy; Deformation; Elastoplasticity; Laboratory tests; Plane strain; Pore pressure; Factor of safety; Shear strength; Shear stress; Shear test; Stiffness; Stress; Strain;

   Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER

3. 2. Manufacturihng of heavy rings and large copper canisters by plastic deformation

   Detta är en avhandling från Stockholm : Industriell produktion

   Författare :Hamzah Ssemakula; KTH.; [2003]
   Nyckelord :pores; grain size; low forginnig load; effective strain;

   Sammanfattning : Plastic deformation processes transform material fromas-received state to products meeting certain requirements inproperties, microstructure and shape. To achieve thistransformation, the relationship between material response andprocess conditions should be understood. LÄS MER

5. 4. High Strain Fatigue Crack Growth and Crack Closure

   Detta är en avhandling från Department of Mechanical Engineering

   Författare :Michael Andersson; Lunds universitet.; Lund University.; [2005]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Materiallära; materialteknik; Material technology; crack closure; high strain fatigue; crack grotwh;

   Sammanfattning : Understanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. LÄS MER

7. 5. Long Term Settlements in Soft Clays

   Detta är en avhandling från Chalmers University of Technology

   Författare :Peter Claesson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lightly overconsolidated soft clay; deep layers; consolidation; settlements; creep; stress-strain-strain rate; calculation model; case records;

   Sammanfattning : When structures are founded on deep layers of lightly overconsolidated, soft clay large settlement often occur during a long period of time after completion of the structure. Therefore it is of major importance to be able to calculate and predict the expected settlements with a satisfactory degree of accuracy, as this has a great impact on the design of the foundation and the possible need for soil improvements.
