11. Testing and Evaluation of Interfibre Joint Strength under Mixed-Mode Loading
Sammanfattning : The failure properties of interfibre bonds are the key for the build-up of strength in fibrous materials such as paper and paperboard. In order to tailor the properties of such materials by chemical or mechanical treatments and to learn how such modifications influence the properties at a microscopic level, direct measurement of individual fibre--fibre crosses are typically performed.

12. Resilient and permanent deformation behavior of unbound aggregates under repeated loading
Sammanfattning : During recent decades, growing interest in the developmentof so-called analytical or mechanistic road pavement designmethods has resulted in substantial research into themechanical behavior of the materials involved. In flexiblepavements, especially when unsurfaced or thinly surfaced,overall structural performance is largely dependent on thebehavior of the unbound granular base and subbase layers. LÄS MER
13. Mechanical and Hydromechanical Behaviour of Hard Rock Joints. A laboratory study
Sammanfattning : As a consequence of rock engineering works, the rock mass will deform due to stress changes. Most deformation occurs in the rock joints, in form of normal and shear strains. These deformations will also change the void geometry and thereby the joint aperture and fluid flow. LÄS MER
14. Active Health Monitoring of Aerospace Composite Structures by Embedded Piezoceramic Transducers
Sammanfattning : The objectives of the thesis work were to study theinteraction between embedded piezoceramic transducers andcomposite structures as well as determine techniques tosimplify the Lamb waves analysis. Firstly, this studyconsidered the design of the embedded piezoceramic transducers. LÄS MER
15. Stimulation of tendon repair by platelet concentrate, CDMP-2 and mechanical loading in animal models
Sammanfattning : Growth factor delivery may be useful to accelerate the rate of tendon healing. We studied Platelet Concentrate, which in effect can be regarded as a cocktail of growth factors relevant for tendon healing. LÄS MER
