  1. 1. Measuring material properties of thin films with DIC and tearing test of laminate

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Peter Nilsson; [2017]
    Keywords : DIC; Thin polymer films; Laminated tearing;

    Abstract : Thin polymer materials are today widely used in industry and production. An ordinary food package can have around six different layers of materials laminated together to obtain the desired protection. To obtain an efficient usage of these materials simulations are often required. READ MORE

  2. 2. The possibility of utilizing the normal incidence reflection coefficient of acoustic waves to characterize and study porous granular layers

    University essay from KTH/Väg- och banteknik

    Author : Hailegiorgis Dinagdae Yared; [2011]
    Keywords : non-destructive testing; reflection coefficient; acoustic wave; porous granular;

    Abstract : currently operational non-destructive testing methods for pavements have many drawbacks that need improvement. This thesis investigates the possibility of utilizing the normal incidence reflection coefficient of acoustic waves in characterizing and studying of porous granular materials. READ MORE

  3. 3. Analysis of strains in cast iron joints using FE-simulations and digital image correlation techniques

    University essay from Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Author : Andreas Autio; Kristoffer Odnegård; [2011]
    Keywords : Metalock; mechanical joining; cast iron; digital image correlation; strain field; finite element analysis.;

    Abstract : The Metalock method is a mechanical joining technique most commonly employed in cracked castings of iron, aluminum and steel. It is based on inserting custom-made “keys”, which are meant to take up tensile and shear stresses, perpendicular to the crack. READ MORE

  4. 4. Nonlinear Non-Destructive Testing of ship hull composites

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Johan Larsson; Daniel Pettersson; [2004]
    Keywords : Non-contact testing; Non-Destructive Testing; Ultrasonic testing; Nonlinear Wave Modulation Spectroscopy; Sound velocity; Resonance.;

    Abstract : Further development of an existing nonlinear ultrasound Non-Destructive Testing method is performed. The Nonlinear Wave Modulation Spectroscopy method is developed into an automated non-contact testing method. The method detects nonlinearities, such as cracks and delaminations, in a test object.
