2. 1. Cost Optimization of Aircraft Structures

   Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

   Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE

4. 2. 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

5. 3. Carbon nanofiller reinforced UHMWPE for orthopaedic applications : optimization of manufacturing parameters

   Author : Evelina Enqvist; Mats Johansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : Polymer composites research designed for orthopaedic applications are commonly focused on Ultra high molecular weight polyethylene (UHMWPE) reinforced by a variety of different nanoparticles. However, the high melt viscosity of UHMWPE renders conventional melt mixing techniques impossible for composite manufacturing. READ MORE

6. 4. On Characterization and Optimization of Engineering Surfaces

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stylus Profilometer; Manufacturing; Coherence Scanning Interferometer; Regression; Areal surface parameters; Characterization; Functional surfaces; Surface profile parameters;

   Abstract : Swedish manufacturing industry in collaboration with academia is exploring innovative ways to manufacture eco-efficient and resource efficient products. Consequently, improving manufacturing efficiency and quality has become the priority for the manufacturing sector to remain competitive in a sustainable way. READ MORE

7. 5. On optimization of natural convection flows

   Author : Clio Saglietti; Dan S. Henningson; Kurt Maute; KTH; []
   Keywords : Natural convection cooling; topology optimization; flow optimization; heat sink; conjugate heat transfer; differentially heated cavity; optimal initial disturbances; adjoint optimization;

   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. READ MORE
