Multiscale Modeling of the Polyamide 11 Hydrolytic Degradation for Offshore Industry Applications: Comparison between model predictions and experimental aging
(Doctoral thesis at NTNU;2015:330, Doctoral thesis, 2015)Hydrolytic degradation at elevated temperatures is a key reason for failure in offshore flexible risers. Polyamide 11 (PA11) is one of the most common materials used for the internal pressure sheaths in flexible risers due ... -
Multiscale Modelling of Environmental Degradation—First Steps
(Chapter, 2018)Fibre-reinforced plastics are praised for their good corrosion resistance. However, when this resistance needs to be documented for safety-critical applications extensive and time-consuming test programmes are needed. A ... -
Multiscale modelling of fiber composites - Investigating micromechanics of constituents' interaction
(Master thesis, 2018)The objectives of this thesis have been to develop a script for a multiscale method based on first order homogenisation, to investigate estimation of properties and behaviour of unidirectional (UD) fiber composites. To ... -

Nano ski wax, effects and benefits
(Master thesis, 2013)The effects of the gliding properties of ski waxes are often discussed and many speculations and assumptions are made. However there are not many studies and documented results in this field. This project is carried out ... -
Nanomechanical Fracture Testing of Diatoms
(Master thesis, 2015)A way to test the fracture properties of the foramen layer has been developed and tested. Cantilevers made out of the diatom silica were produced with the Focused Ion Beam (FIB). These had notches milled close to the base ... -
NANOMECHANICAL TESTING OF CGHAZ OF ARCTIC STEEL
(Master thesis, 2015)An ever increasing demand for energy is forcing the oil industry to push technology forward, as new oil rich fields are discovered further North. The Arctic offers a harsh, cold climate, leading to new challenges within ... -
Nanomechanical Testing of Diatoms
(Master thesis, 2013)Diatoms, a major group of algea, are protected by a nanostructured shell, built with a design that exceeds the capabilities of human engineering. These shells, termed frustules, consist of biosilica and give the organism ... -
NANOMECHANICAL TESTING OF DIATOMS
(Master thesis, 2012)A test scheme to test micro-beams from diatom frustule has been developed. The method is capable of testing both complete beams and beams made from the individual layers of the frustule. The biosilica is shown to be a very ... -
