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

   Abstract : This study summarizes previous research to evaluate and verify the results of the extensive restoration of The Basilica of Santa Maria di Collemaggio after the 2009 L’Aquila earthquake. In addition, it aims at identifying the vulnerability factors and challenges in preserving these buildings. READ MORE

4. 3. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

   University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Christian Nielsen; [2015]
   Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

   Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE

5. 4. Damage detection on railway bridges using Artificial Neural Network and train induced vibrations

   University essay from KTH/Bro- och stålbyggnad

   Author : Jiangpeng Shu; Ziye Zhang; [2012]
   Keywords : Damage detection; Railway Bridge; Dynamic Response; high-speed trains; Statistical Property; Artificial Neural Network ANN ;

   Abstract : A damage detection approach based on Artificial Neural Network (ANN), using the statistics of structural dynamic responses as the damage index, is proposed in this study for Structural Health Monitoring (SHM). Based on the sensitivity analysis, the feasibility of using the changes of variances and covariance of dynamic responses of railway bridges under moving trains as the indices for damage detection is evaluated.

6. 5. Data Processing Algorithms in Wireless Sensor Networks får Structural Health Monitoring

   University essay from KTH/Bro- och stålbyggnad

   Author : Nigatu Mitiku Danna; Esayas Getachew Mekonnen; [2012]
   Keywords : Bridge; FFT; Modal Analysis; Monitoring; Natural Frequency; Peak Picking; Structure; Wireless Sensor.;

   Abstract : The gradual deterioration and failure of old buildings, bridges and other civil engineering structures invoked the need for Structural Health Monitoring (SHM) systems to develop a means to monitor the health of structures. Dozens of sensing, processing and monitoring mechanisms have been implemented and widely deployed with wired sensors. READ MORE
