1. Fractured Rock Masses as Equivalent Continua - A Numerical Study
Sammanfattning : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.

2. Determination of equivalent hydraulic and mechanical properties of fractured rock masses using the distinct element method
Sammanfattning : The equivalent continuum approach uses equivalent propertiesof rock mass as the input data for a continuum analysis. Thisis a common modeling method used in the field of rock mechanicsand hydrogeology. LÄS MER
3. Upscaling of Flow, Transport, and Stress-effects in Fractured Rock
Sammanfattning : One of many applications of geohydraulic modelling is assessing the suitability of a site to host a nuclear waste repository. This modelling task is complicated by scale-dependent heterogeneity and coupled thermo-hydro-mechanical (THM) processes. LÄS MER
4. On Methods for Discrete Topology Optimization of Continuum Structures
Sammanfattning : This thesis consists of an introduction and seven appended papers. The purpose of the introduction is to give an overview of the field of topology optimization of discretized load carrying continuum structures. LÄS MER
5. On the Escape of Lyman Radiation from Local Galaxies
Sammanfattning : Cosmic reionization was most likely initiated by star forming dwarf galaxies. Little is known about the physical mechanisms allowing ionizing Lyman continuum (LyC) photons to escape from galaxies, but to learn more we can study local galaxies in detail. LÄS MER
