6. Surface Wave Testing of Pavements
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

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

8. Combined speckle interferometry and speckle correlation for non-destructive testing
Abstract : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. READ MORE

9. Ultrasonic testing of components produced with additive manufacturing : Towards improved detection and classification of defects
Abstract : The focus in this work is on the use of ultrasonic testing as a method for inspecting components manufactured through additive manufacturing (AM) processes. The research is rooted in the need for effective non-destructive testingtechniques that can adapt to the unique challenges posed by AM-produced materials, including complex defect geometries and surface conditions.

10. Mechanical Characterization of Engineering Materials by Modal Testing
Abstract : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).
