  1. 1. Application of Lamb waves using piezoelectric technique for structure health monitoring

    University essay from KTH/Hälsoinformatik och logistik

    Author : Simon Mauritz; [2023]
    Keywords : Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Abstract : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. READ MORE

  3. 2. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

  6. 5. Structural Health of a concrete tunnel lining under complex in situ loading

    University essay from KTH/Bro- och stålbyggnad

    Author : LEONARDO DALLA ROSA; [2019]
    Keywords : ;

    Abstract : Supporting structures were designed for a utility tunnel in hard rock which was to be intersectedby some road tunnels. With the intersections involving partial overlapping between the idealcross-sections, a concrete lining and post-tensioned steel cables were added to support theutility tunnel prior to the excavation of the road tunnels.
