1. Transmission of waves through elastic and viscoelastic junctions
Sammanfattning : Transmission of extensional waves through elastic and viscoelastic junctions between elastic and collinear bars have been studied theoretically and experimentally. The models used can be interpreted also for other types of waves (e.g. dilatational waves, shear waves, electromagnetic waves) and systems. LÄS MER
2. Identification of viscoelastic materials and continuous-time stochastic systems
Sammanfattning : Two system identification problems, identification of viscoelastic material properties and identification of continuous-time stochastic systems, are considered in the thesis. The viscoelastic material properties are characterised by the frequency-dependent complex modulus. LÄS MER
3. Rheological Properties of Microfibrillated Cellulose
Sammanfattning : Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. LÄS MER
4. Mircostructure and rheological properties of concentrated tomato suspensions during processing
Sammanfattning : Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural and rheological properties of the material.

5. On the Design and Life Prediction of Transmission Belts Made of Elastomer Composites
Sammanfattning : Next to gear transmissions, belt transmissions are the most important mechanical transmissions. Today, belt design and development is based on extensive application tests of belts in the product development process. There is a need for theory development and design support systems. LÄS MER
