  1. 1. Hardening concrete measurments and evaluation of non-elastic deformation and associated restraint stresses

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Hans Hedlund; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : If a structural member of hardening concrete is restrained to some degree against expansion and contraction during the heating phase of the hydration process and the subsequent contraction phase, stresses will be induced. The issue of primary interest is whether or not these induced stresses will lead to cracking. LÄS MER

  2. 2. Hardening Distortions of Serial Produced Gears

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; Arne Melander; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER

  4. 4. Modelling mechanical properties by analysing datasets of commercial alloys

    Detta är en avhandling från Stockholm : KTH

    Författare :Johan Zander; Rolf Sandström; Stanislaw Zajac; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloys; modelling; material optimisation; mechanical properties; solid solution hardening; precipitation hardening; work-hardening; multiple regression; stainless steel; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. LÄS MER
