2. 1. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty

   Author : Dženan Hozić; Carl-Johan Thore; François-Xavier Irisarri; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Optimization; Composite Structures; Topology Optimization; Multi-material Optimization; Material Uncertainty; Robust Optimization; Composite Structure Optimization; Design Optimization; Composite Material;

   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

4. 2. Ride Comfort Optimization of Buses

   Author : Peter Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural vibrations; FEM; global optimization; ride comfort; roll control system; MBS; optimization; bus; road irregularities; sensitivity analysis;

   Abstract : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. READ MORE

6. 4. Approximation of topology optimization problems using sizing optimization problems

   Author : Anton Evgrafov; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; structural optimization; bilevel programming; approximation; topology optimization; control in coefficients; optimal design; fictitious domain; control in coefficients;

   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

7. 5. Slab Frame Bridges : Structural Optimization Considering Investment Cost and Environmental Impacts

   Author : Majid Solat Yavari; Costin Pacoste-Calmanovici; Raid Karoumi; Mario Plos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slab frame bridge; Structural design; Cost optimization; Optimization of environmental impact; Life cycle assessment; Genetic algorithm; Pattern search method; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge.
