2. BEM analysis of the single fiber fragmentation test
Abstract : A Boundary Element analysis of micromechanical elastic fields in the single-fiber fragmentation test is presented in this thesis. The work carried out is roughly divided in two main tasks: the development of the BE code and the numerical simulation of the single-fiber fragmentation test. READ MORE

3. Dendrimers and dendronized polymers : synthesis and characterization
Abstract : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. READ MORE

4. Fibre flocculation during twin-wire roll forming
Abstract : At the division of Paper Technology a forming unitconsisting of headbox, forming roll unit and reservoir systemfor suspension recirculation has been constructed, with themain purpose to experimentally study the paper forming event byvisually following the fibre flow phenomena in the formingzone.The effect of various running parameters upon the pressuredistribution, which is in correlation to the flow phenomenaoccuring during forming, has been studied with a flush mountedpressure sensor.

5. Numerical analysis of the single fiber fragmentation test including the effect of interfacial friction
Abstract : A numerical analysis of the single fiber fragmentation test is presented in this thesis. The aim of the numerical study is elucidating the influence of friction in the growth of the debond cracks along the fiber-matrix interface. Two distinct approaches and numerical techniques have been employed in the analysis. READ MORE
