  1. 1. Speckle suppression in ultrasound images of heterogeneous materials

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Simon Johnsson; [2023]
    Keywords : Ultrasound; non-destructive testing; wiener filter; signal processing;

    Abstract : Performing non-destructive testing (NDT) on materials is a helpful tool for maintenance and quality control because the materials are not destroyed or disturbed; ultrasound imaging is one type of NDT. Ultrasound imaging of heterogeneous materials contains many echoes from the material itself. READ MORE

  3. 2. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Filip Tuvenvall; [2023]
    Keywords : Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Abstract : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. READ MORE

  4. 3. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kim Klöckner; [2023]
    Keywords : NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

    Abstract : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. READ MORE

  5. 4. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Viktor Svensson; Robin Raymundsson; [2023]
    Keywords : Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Abstract : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. READ MORE

  6. 5. Impact Damage Assessment : In collaboration with Saab aerostructures

    University essay from KTH/Materialvetenskap

    Author : Julia Augustson; Madeleine Bogg; [2020]
    Keywords : ;

    Abstract : This project that has been executed in collaboration with Saab aerostructures deals with how three materials, aluminum, titanium and corrosion resistant steel react when they are affected by different energy levels. These energy levels serve the purpose of representing damages that can happen in storage and handling to components used in production. READ MORE
