  1. 1. Simulation of Stainless Steel Tube Extrusion

    Author : Sofia Hansson; Luleå tekniska universitet; []
    Keywords : 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

    Author : Fan Zhang; Lund Ortopedi; []
    Keywords : meniscus; extrusion; MRI;

    Abstract : .... READ MORE

  3. 3. Tribological aspects of aluminium extrusion dies

    Author : Thomas Björk; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Extrusion; Die; Wear; Tool; Friction; Simulation; Bearing; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Extrusion is a common method to manufacture long products of aluminium, such as beams, rods and tubes. The aim of this thesis was to improve the material in the die bearing surface, and thereby the service life of extrusion dies through wear studies of actual dies, and experimental simulations.

  4. 4. Modeling of the Stainless Steel Tube Extrusion Process

    Author : Sofia Hansson; Erman Tekkaya; Högskolan Dalarna; []
    Keywords : 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

  5. 5. Wheat Gluten -Based Materials and Composites: Extrusion, Casting and Antimicrobial Properties

    Author : Hasan Türe; Mikael Hedenqvist; José-Maria Lagaron; KTH; []
    Keywords : wheat gluten; extrusion; urea; montmorillonite; sol-gel process; hybrid materials; casting; compression moulding; potassium sorbate; antifungal; plasticiser; thermal; mechanical and barrier properties.;

    Abstract : The use of bio-based polymers as packaging materials has gained much attention due to increasing environmental concerns regarding non-biodegradable petroleum-derived plastics. Wheat gluten (WG) is a valuable renewable resource for the production of bio-based materials because of its low price, biodegradability, good film-forming properties and good gas barrier properties under dry conditions.
