  1. 1. Simulation of stainless steel tube extrusion

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Hansson Sofia; Sofia Hansson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulering av extrusion av rostfria rör; Extrusion; finite element method; stainless steel; physically based material model; dislocation density; Material Mechanics; Materialmekanik;

    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

  3. 3. Tribological aspects of aluminium extrusion dies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Thomas Björk; Uppsala universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Extrusion; Die; Wear; Tool; Friction; Simulation; Bearing; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP 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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sofia Hansson; Högskolan Dalarna.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulering av extrusion av rostfria rör; Extrusion; FEM; Stainless steel; Tube; Material Mechanics; Materialmekanik; Technology - Materials science; Teknikvetenskap - Teknisk materialvetenskap;

    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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hasan Türe; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.
