1. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement
Sammanfattning : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. LÄS MER
2. Delayed Hydride Cracking in Irradiated Zircaloy
Sammanfattning : Under some circumstances nuclear fuel cladding tubes made from zirconium based alloys may develop long axial cracks. The formation of these cracks is mainly thought to be connected with the oxiditian and hydriding of the cladding which takes plage after the the formation of a small primary defect. LÄS MER
3. Matrix cracking and interfacial debonding in polymer composites
Sammanfattning : .... LÄS MER
4. Micro-mechanical mechanisms for deformation in polymer-material structures
Sammanfattning : In this thesis, the focus has been on micro-mechanical mechanisms in polymer-based materials and structures. The first part of the thesis treats length-scale effects on polymer materials. Experiments have showed that the smaller the specimen, the stronger is the material. LÄS MER
5. Self-Healing Concrete
Sammanfattning : Concrete is a brittle material prone to cracking due to its low tensile strength. Crack repairs are not only expensive and time-consuming but also increase the carbon footprint. Designing a novel concrete material possessing the ability to self-repair cracks would enhance its sustainability. LÄS MER
