Structural health monitoring of bridges using wireless sensor networks
Structural Health Monitoring, damage detection and localization of bridges using Wireless Sensor Networks (WSN) are studied in this thesis. The continuous monitoring of bridges to detect damage is a very useful tools for preventing unnecessary costly and emergent maintenance. The optimal design …

Νέα προσέγγιση στην παρακολούθηση της αναπτυσσόμενης βλάβης υπό μηχανική φόρτιση σε ινώδη σύνθετα υλικά με μήτρα ενισχυμένη με νανοσωληνίσκους άνθρακα
Η συνεχώς αυξανόμενη χρήση σύνθετων υλικών στην αεροδιαστημική βιομηχανία στις κρίσιμες δομικές εφαρμογές έχει οδηγήσει στην ανάγκη ανάπτυξης μη καταστροφικών μεθόδων βλάβης. Οι έως τώρα χρησιμοποιούμενες μέθοδοι για την παρακολούθησης βλάβης όπως είναι η ενσωμάτωση πιεζο-κεραμικών αισθητήρων και …

Modeling Behaviour of Damaged Turbine Blades for Engine Health Diagnostics and Prognostics
… gas turbine engines is largely due to careful damage tolerant design a method of structural design based on the assumption that flaws (cracks) exist in any structure and will continue to grow with usage. With proper monitoring, largely in the form of periodic inspections at conservative …

High Frequency Modeling and Experimental Analysis for Implementation of Impedance-based Structural Health Monitoring
A promising structural health monitoring (SHM) method for implementation on real world structures is impedance-based health monitoring. An in-service system is envisioned to include on board processing and perhaps wireless transfer of data. Ideally, a system could be produced as a slap-on or …

Bridge-vehicle interaction for structural health monitoring: potentials, applications, and limitations
Structural Health Monitoring (SHM) is an integral part of infrastructure maintenance and management systems due to socio-economic, safety and security reasons. The behaviour of a structure under vibration depends on structure characteristics. The change of structure characteristics may suggest the …

Inverse Problems In Structural Damage Identification, Structural Optimization, And Optical Medical Imaging Using Artificial Neural Networks
… The inverse problems investigated are: 1) damage detection in structures, 2) detection of an anomaly in a light-diffusive medium, such as human tissue using optical imaging, 3) structural optimization of fiber optic sensor design. All of these problems require solving highly complex inverse …

Nonlinear System Identification of Physical Parameters for Damage Prognosis and Localization in Structures
… the period of crack growth. To date, structural health monitoring approaches that seek to detect cracks offer no insight into the extent of deterioration occurring in the initial stage that is a precursor to the formation of the microcrack or its growth. However, an approach that would facilitate …

Leveraging Carbon Based Nanoparticle Dispersions for Fracture Toughness Enhancement and Electro-mechanical Sensing in Multifunctional Composites
… experimental investigations, the strain and damage sensing abilities of multi-walled carbon nanotube (MWCNT) networks embedded in the binder phase of polymer bonded energetics (PBEs) are evaluated. PBEs are a special class of particulate composite materials that consist of energetic crystals …
