1. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests
Sammanfattning : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

2. Spin ice under uniaxial pressure and magnetic frustration in garnets
Sammanfattning : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. LÄS MER
3. Effect of large shear deformation on fatigue crack behavior in pearlitic rail steel
Sammanfattning : The impacts from global warming and climate change continue to rise and securing the needs of future generations requires a transition to a climate-neutral society. Rail transportation, as being one of the safest and most energy efficient modes of transportation offers a sustainable alternative to fossil-fueled based transportation. LÄS MER
4. Electronic Structure of Transition Metal Complexes in Silicon
Sammanfattning : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. LÄS MER
5. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation
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.
