1. Long Term Settlements in Soft Clays
Abstract : 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.

2. On the Modelling of Mechanical Dewatering in Papermaking
Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

3. Exploring Biopolymer-Clay Nanocomposite Materials by Molecular Modelling
Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

4. The Plastic Flow Behaviour of Aluminium Alloys Exhibiting Dynamic Strain Ageing
Abstract : The phenomenon known as dynamic strain ageing, abbreviated DSA, has been known since the beginning of last century. It was first discovered as serrations in the load-elongation curve obtained upon deforming specimens of certain alloys in tension. This phenomenon became known as the Portevin-Le Chatelier (PLC) effect. READ MORE

5. Fatigue behaviour of a nickel based superalloy
Abstract : This thesis deals with different aspects of fatigue crack propagation in IN718. The ultimate objective of the work is to gain understanding of the fatigue process, from the macroscopic stress-strain relations to microscopic fatigue crack growth mechanisms. READ MORE
