1. Process development for investment casting of thin-walled components : Manufacturing of light weight components
Sammanfattning : Manufacturing processes are getting more and more complex with increasing demands of advanced and light weight engineering components, especially in aerospace industry. The global requirements on lower fuel consumption and emissions are increasing the demands in lowering weight of cast components. LÄS MER
2. Characterisation of Time-dependent Statistical Failure of Fibre Networks : Applications for Light-weight Structural Composites
Sammanfattning : The future of a sustainable society requires that materials not only be renewable, but also leave as small a carbon foot-printin the environment as possible. One such product is light-weight composite material for transportation packages. Cellulose fibres have been and will continue to be ideal for this purpose. LÄS MER
3. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design
Sammanfattning : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. LÄS MER
4. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER
5. Flip-Chip Interconnect for Millimeter-Wave Packaging Applications
Sammanfattning : In recent years, with the demands for wireless communication systems increas rapidly, the operating frequency for the portable wireless is moving toward millimeter-waves. Millimeter-wave wireless communication systems require not only suitable functional IC components but also competent package with low cost and good interconnect performance. LÄS MER
