1. Analysis and Modelling of Mineral and Element Composition in Compression Breakage
Sammanfattning : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. The growing interest due to the high economic importance and the limited supply places these metals in the critical metals risk list. LÄS MER
2. Modeling of foams for impact simulations
Sammanfattning : Stimulated by the strong drive in the automotive industry to reduce energy consumption,and, linked to that, the need to reduce weight, this thesis concerns modeling of foams forimpact simulations. To start with, a continuum hyperelasto-viscoplastic model is developedwithin the framework of Theory of Porous Media. LÄS MER
3. Optimization of Vehicle Structures under Uncertainties
Sammanfattning : Advancements in simulation tools and computer power have made it possible to incorporate simulation-based structural optimization in the automotive product development process. However, deterministic optimization without considering uncertainties such as variations in material properties, geometry or loading conditions might result in unreliable optimum designs. LÄS MER
4. Rotation-free shell elements for thin-film structures and simulations of centrifugally deployed spece webs
Sammanfattning : .... LÄS MER
5. Muscular forces from static optimization
Sammanfattning : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. LÄS MER
