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
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
2. In-Plane Fracture of Paper
Detta är en avhandling från Structural Mechanics, Lund UniversitySammanfattning : The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. LÄS MER
3. Strain and Charge Transport in InAsP-InP and InP-InAs Core-Shell Nanowires
Detta är en avhandling från Department of Physics, Lund UniversitySammanfattning : The mechanical, optical, and electrical properties of III-V semiconductor heterostructures are investigated in thisthesis. The semiconductor materials are grown by metal-organic vapor phase epitaxy, yielding wire shaped crystals(nanowires) having a length of ~ 1 μm and diameter of ~ 100 nm. LÄS MER
4. Growth and Characterization of Strain-engineered Si/SiGe Heterostructures Prepared by Molecular Beam Epitaxy
Detta är en avhandling från Linköping : Linköping University Electronic PressSammanfattning : The strain introduced by lattice mismatch is a built-in characteristic in Si/SiGe heterostructures, which has significant influences on various material properties. Proper design and precise control of strain within Si/SiGe heterostructures, i.e. LÄS MER
5. Multiscale granular mechanics: A neutron diffraction based experimental approach
Detta är en avhandling från Division of solid mechanics, Lund UniversitySammanfattning : Granular media (i.e., assemblies of grains, containing voids), such as sand, are highly complex materials, possessing inherently heterogeneous structure and properties that are manifested by the mobility and interaction of their constituent particles. Despite having been widely studied for centuries (i. LÄS MER
