  2. 1. Silicone Rubber Insulators: Impacts of Material Formulation in Coastal Environment

    Author : Tomas G Gustavsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface characterization; aging; filler level; outdoor insulation; leakage current measurements; material formulation; silicone rubber; polymeric insulators; coastal environment; polydimethylsiloxane PDMS ;

    Abstract : This thesis deals with influences of material formulation on the performance of silicone rubber high voltage insulators in a coastal environment. Samples and insulators with known differences in material compositions have been used in this task. In the first step, a screening test with cylindrical samples was initiated. READ MORE

  5. 3. Dislocation density based material model applied in FE-simulation of metal cutting

    Author : Dan Wedberg; Bevis Hutchinson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Simulation based design enables rapid development of products with increased customer value in terms of accessibility, quality, productivity and profitability. However simulation of metal cutting is complex both in terms of numeric and physics. The work piece material undergoes severe deformations. READ MORE

  6. 4. Botulinum Toxin : Formulation, Concentration and Treatment

    Author : Alma Rystedt; Dag Nyholm; Carl Swartling; Klas Nordlind; Uppsala universitet; []
