  2. 1. Robust design : Accounting for uncertainties in engineering

    Author : David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

    Abstract : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  4. 2. Simulation of Stainless Steel Tube Extrusion

    Author : Sofia Hansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extrusion; finite element method; stainless steel; physically based material model; dislocation density; Simulering av extrusion av rostfria rör; Material Mechanics;

    Abstract : The simulation of hot extrusion processes is a difficult and challenging problem in process modeling. This is due to very large deformations, high strain rates and large temperature changes during the process. READ MORE

  5. 3. Modeling of the Stainless Steel Tube Extrusion Process

    Author : Sofia Hansson; Erman Tekkaya; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extrusion; FEM; Stainless steel; Tube; Simulering av extrusion av rostfria rör; Material Mechanics;

    Abstract : Seamless tubes of stainless steel can be extruded using glass as a lubricant in the Ugine-Sejournet process. The process is performed at high temperature and is associated with large deformations and high strain rates. READ MORE

  6. 4. Melt-processing and properties of thermoplastic composites based on ethylene-acrylic acid copolymer reinforced with wood nanocellulose

    Author : Abhijit Venkatesh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp fibers; Melt rheology; Composite; Injection moulding; Cellulose; Cellulose nanofibers; Cellulose nanocrystals; Extrusion; Mechanical properties;

    Abstract : Composites reinforced with cellulose nanofibers (CNF), both modified and unmodified cellulose nanocrystals (CNC) and pulp fibers have been prepared through small-scale and large-scale methods. The composites were produced by water-assisted dispersion mixing, drying and compression moulding on the laboratory scale and by extrusion and injection moulding for the large-scale production.

  7. 5. Integrated Product and Process Design for Mass Customization: A Road Towards Patient Access to Individualized Pharmaceutical Therapy

    Author : Rydvikha Govender; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hot melt extrusion; mass customization; modularization; integration; fused deposition modelling; individualized therapy; pharmaceutical manufacturing; reconfiguration; polymeric solid dispersion; patient-centric product design;

    Abstract : Individualized pharmaceutical therapy strives to attain optimal health outcomes a priori in all patients treated with pharmaceutical products by tailoring these products to each patient’s holistic needs. However, existing mass-produced pharmaceutical products are not available in sufficient variety to enable adequate tailoring to the diverse needs of individuals. READ MORE
