1. Fatigue crack growth experiments and analyses - from small scale to large scale yielding at constant and variable amplitude loading
Sammanfattning : This thesis is on fatigue crack growth experiments and assessments of fatigue crack growth rates. Both constant and variable amplitude loads in two different materials are considered; a nickel based super-alloy Inconel 718 and a stainless steel 316L. LÄS MER
2. On crack growth under compressive stresses
Sammanfattning : This thesis concerns fractures subjected to compressive stresses. In the four papers appended fracture behavior in brittle as well as ductile materials is studied. LÄS MER
3. On fracture of layered materials
Sammanfattning : This thesis is concerned with fracture in layered bimaterials. Fracture of coatings is considered to some extent. The behaviour of cracks growing normal to bimaterial interfaces is studied with the objective to clarify conditions for crack-tip shielding and amplification. LÄS MER
4. Fatigue of Metal Matrix Composites
Sammanfattning : This thesis treats the mechanical properties of discontinuously reinforced metal matrix composites, DMMCs, in general and their fatigue properties in particular. Methods of manufacture, microstructures and resulting mechanical properties of DMMCs are reviewed in the introductory part. LÄS MER
5. Mechanics of microdamage development and stiffness degradation in fiber composites
Sammanfattning : Damage in composites reduces its performance and durability and thus its usefulness. The common subject in all papers presented in the licentiate thesis is distributed microdamage, and the materials of interest are a Hemp/Lignin natural composite and glass/carbon fiber reinforced plastics composites.
