  1. 21. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Författare :Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Sammanfattning : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

  4. 23. Kinematics and Internal Deformation of Granular Slopes

    Författare :Zhina Liu; Hemin Koyi; Dominique Frizon de Lamotte; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; granular flow; kinematics; internal deformation; particle flow method; analogue modeling; natural landslides; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Flow-like mass movement is the most destructive landslide and causes loss of lives and substantial property damage throughout the world every year. This thesis focuses on the spatial and temporal changes of the mass movement in terms of velocity and displacement within the failure mass, and the spatial and temporal distribution of the three dimensional internal deformation of the granular slopes using discrete element method, physical experiments, and natural landslides.

  5. 24. Viscous-brittle deformation of shallowly emplaced silicic magma : Implications for outgassing and volcanic hazards

    Författare :Taylor Witcher; Steffi Burchardt; Edward Llewellin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magma deformation; magmatic outgassing; magmatic intrusions; rhyolite; Sandfell laccolith; crystal mush; volcanic hazards; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Silicic magma in the shallow crust has the potential to violently erupt, depending on its ability to release overpressures caused by magmatic volatiles (outgassing). Deformation-induced outgassing is prevalent along volcanic conduit margins, where ascending magma is sheared at high rates. LÄS MER

  7. 25. Configuration spaces, props and wheel-free deformation quantization
