21. Long Term Settlements in Soft Clays
Sammanfattning : When structures are founded on deep layers of lightly overconsolidated, soft clay large settlement often occur during a long period of time after completion of the structure. Therefore it is of major importance to be able to calculate and predict the expected settlements with a satisfactory degree of accuracy, as this has a great impact on the design of the foundation and the possible need for soil improvements.

22. Hygro-Mechanics of Wood Fibre Composite Materials
Sammanfattning : The work presented in this thesis deals with modelling and testing of hygro-mechanical properties of wood fibre composite materials. The material studied experimentally is high pressure laminate, HPL, which is a wood fibre network composite, made up of craft paper impregnated with phenolic or melamine resin. LÄS MER
23. Silicon Carbide Reinforced Alumina and Mullite Ceramics
Sammanfattning : The aim of this work was to develop homogeneous ceramic nanocomposite materials with good thermal and structural stability as well as good mechanical properties. The development of microstructure was related to the material properties. LÄS MER
24. On Probability in Geotechnics. Random Calculation Models Exemplified on Slope Stability Analysis and Ground-Superstructure Interaction
Sammanfattning : The thesis deals with uncertainty in calculation modelling. Emphasis is put on the design state. Design is a chain of decisions under uncertainty. A probabilistic approach is used to describe the uncertainty and calculations as a way to reveal the uncertainty. LÄS MER
25. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa
Sammanfattning : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. LÄS MER
