1. Structural Design of Laser-Welded Sandwich Panels for Marine Applications
Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

2. Magneto-sensitive rubber in the audible frequency range
Sammanfattning : The dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber is the focus of this thesis consisting of five papers A-E. Paper A presents results drawn from experiments on samples subjected to different constant shear strains over varying frequencies and magnetic fields. LÄS MER
3. Application of Automated Non-contact Resonance Testing for Low Temperature Behavior of Asphalt Concrete
Sammanfattning : Impact resonance testing is a well-documented non-destructive testing method and its applications on asphalt concrete have also been implemented successfully. The test is carried out manually by inducing an impact in order to excite the test specimen and taking measurements of the vibrational response. LÄS MER
4. Micromechanical Modelling of Wood and Fibre Properties
Sammanfattning : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. LÄS MER
5. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations
Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER
