  1. 1. Surfaces Designed for High and Low Friction

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Ulrika Pettersson; Uppsala universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; tribology; friction; surface texture; surface design; low friction; high friction; boundary lubrication; DLC; embossing; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : This thesis comprises tribological studies of extremely well-defined surfaces of different designs. Both low-friction and high-friction surfaces were manufactured and experimentally evaluated.In the low-friction studies, lithography and anisotropic etching of silicon was first used as a texturing technique.

  4. 4. Fracture mechanical modelling of embossed paper

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Rickard Hägglund; Malmö University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Technology;

    Abstract : This thesis consists of two scientific papers on strength and fracture of embossed tissue paper. In Paper A an experimental study of embossed tissue paper is presented. The mechanical properties of most soft tissue paper are to a large extent governed by the creping and subsequent embossing process. READ MORE
