  1. 1. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

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

    Sammanfattning : 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. LÄS MER

  3. 2. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Design of an encoder converter forautomated non-destructive testing

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Per von Wowern; [2018]
    Nyckelord :;

    Sammanfattning : WesDyne Sweden AB is a Non-Destructive Testing (NDT) company specializedin the examination methods ultrasonic testing, eddy current testing and visualinspection. To verify an examination procedure before the actual inspection atsite, a test rig consisting of a three or four axes motion system is used. LÄS MER

  5. 4. Bending properties of commercial wood-based panels by NDT methods

    Master-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Francesco Poggi; [2017]
    Nyckelord :Wood-based panels; Non-destructive testing; Bending properties; Resonance vibration; Time-of-flight; Modulus of elasticity; Modulus of rupture; Stress wave velocity; Relative humidity.;

    Sammanfattning : This thesis work focuses mainly on the application of non-destructive testing (NDT) methods on wood-based panels (WBP) in order to estimate the bending properties. To prove the accuracy and applicability of these methods on WBP, their results are correlated with results from a standardized static bending test. LÄS MER
