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. 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
3. Rheology of Wheat Flour Doughs at Large Deformations and the Relation to Baking Quality and Physical Structure
Sammanfattning : The effects on dough rheology at large deformations in elongational flow and shear flow have been studied. The results are related to bread making quality in terms of bread volume and to the physical structure of the dough. A new method for evaluation of an instrumented mixograph is reported. LÄS MER
4. Fracture and stress in powder compacts
Sammanfattning : In the field of powder metallurgy (PM), the production methods are constantly developed and improved to produce components with high precision and strength. Cold uniaxial pressing of powder into a green body is a common process in PM. LÄS MER
5. Analysis of rock stress and rock stress measurements with application to Äspö HRL
Sammanfattning : The process of choosing a site for a nuclear waste repository means that many aspects have to be taken into consideration. One of these is that the repository has to be mechanically stable for a long time. The mechanical stability of the rock is very difficult to determine. LÄS MER
