  1. 1. Towards Automation of Non-Destructive Testing of Welds

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Patrik Broberg; Högskolan Väst.; Luleå tekniska universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell arbetsvetenskap; Industrial engineering; Welding; non-destructive testing; NDT; Experimentell mekanik; Experimental Mechanics;

    Abstract : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

  3. 3. In-situ assessment of density and material properties in timber structures by non-destructive and semi-destructive testing

    University dissertation from Stockholm : Department of Psychology, Stockholm University

    Author : Thomas Kruglowa; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray; Vasa warship.; semi-destructive testing SDT ; density determination; non-destructive testing NDT ; calibration procedure; Keywords: In-situ assessment;

    Abstract : ABSTRACTIn the assessment of timber structures, diagnostic investigations of the structural members and connections are generally necessary. The assessment often requires appropriate non-destructive testing (NDT) and semi-destructive testing (SDT) techniques. READ MORE

  4. 4. Surface Wave Testing of Pavements

    University dissertation from Nils Ryden, Department of Engineering Gelogy, Lund Institute of Technology, Lund University, BOX 118, 22100 Lund

    Author : Nils Rydén; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

    Abstract : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. READ MORE

  5. 5. Non destructive testing methods for integrity determination of concrete structures

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jon Rasmussen; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Abstract : The ageing of concrete structures can be a threat to human safety as well as being a huge economical factor in the near future. Lifetime prediction and damage assessment of concrete structures will be a growing part of infrastructure planning. READ MORE
