1. Tensile fracture of ice : test methods and fracture mechanics analysis
Sammanfattning : This thesis is concerned with several aspects of fracture of both brackish (low salinity) sea ice and freshwater ice. The tests and analyses are confined to tensile, or in fracture mechanics language, Mode I, fracture. LÄS MER
2. 3D printing of polymers onto textiles : An innovative approach to develop functional textiles
Sammanfattning : This thesis aims at characterizing tridimensional (3D) printed polymers onto PET textile materials via fused deposition modeling (FDM) that uses both non-conductive and conductive polymers, optimizing their mechanical and electrical properties through statistical modeling and enhancing them with pre and post-treatments and the development of polymer blends. This research work supports the development of technical textiles through 3D printing that may have functionalities. LÄS MER
3. Microstructure and mechanical properties of Ti-6Al-2Sn-4Zr-2Mo and Ti-6Al-4V : influence of H, O and B
Sammanfattning : Titanium and its alloys are used in a wide range of applications from aerospace, marine, biomedical implants and consumer goods, due to their superior specific strength, excellent corrosion resistance, and biocompatibility. In aerospace applications, these alloys are predominately used as components in the aero/rocket engines because of their high strength-to-density ratio compared to other metallic materials. LÄS MER
4. Effects of Cell Wall Structure on Tensile Properties of Hardwood : Effect of down-regulation of lignin on mechanical performance of transgenic hybrid aspen. Effect of chemical degradation on mechanical performance of archaeological oak from the Vasa ship
Sammanfattning : Wood is a complex material and the mechanical properties are influencedby a number of structural parameters. The objective of this study has been toinvestigate the relationship between the structure and the mechanical propertiesof hardwood. Two levels were of special interest, viz. LÄS MER
5. Development and characterisation of bast and basalt fibre hybrid polymer composites for automotive applications
Sammanfattning : Natural fibres such as kenaf, hemp, and flax, also known as bast fibres, offer several benefits such as low density, low cost, carbon dioxide neutrality, sustainability and renewability. In Europe, their composites are used intensively by almost all car manufacturers, mostly in interior applications. LÄS MER
