1. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty
Abstract : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. READ MORE

2. Approximation of topology optimization problems using sizing optimization problems
Abstract : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. READ MORE

3. Topology optimization of vehicle structures
Abstract : This thesis concerns topology optimization of vehicle structures. Vehicle structures are considered to be composed of beams joined together and the work has been focused on a method for beam topology optimization including joints. READ MORE

4. Topology optimization of transitional flows
Abstract : This thesis is concerned with the application of topology optimization in thedesign of structures that control fluids. A framework is developed in the high-order Spectral Element Method (SEM) code Nek5000, extending Nek5000 fromits original capabilities, performing Direct Numerical Simulations (DNS), toperforming density-based topology optimization.

5. On optimization of natural convection flows
Abstract : Two different techniques are presented for enhancing the thermal performance of natural convection cooled heat sinks. The physics is described by solving the conjugate heat transfer problem with a spectral element method. The temperature distribution is computed in two sub-domains, whose solution is then conjugated.
