Damage detection and structural health monitoring of ST-37 plate using smart materials and signal processing by artificial neural networks
Structural health monitoring (SHM) systems operate online and test different materials using ultrasonic guided waves and piezoelectric smart materials. These systems are permanently installed on the structures and display information on the monitor screen. The user informs the engineers of the existing damage after observing signal loss which appears after damage is caused. In this paper health...
متن کاملDamage Detection with Streamlined Structural Health Monitoring Data
The huge amounts of sensor data generated by large scale sensor networks in on-line structural health monitoring (SHM) systems often overwhelms the systems' capacity for data transmission and analysis. This paper presents a new concept for an integrated SHM system in which a streamlined data flow is used as a unifying thread to integrate the individual components of on-line SHM systems. Such an...
متن کاملAggressive Data Reduction for Damage Detection in Structural Health Monitoring
While wireless sensors are increasingly adopted in various applications, the need of developing data reduction methods to alleviate data transmission rate issue between the sensors and the data interpretation unit becomes more urgent. This article presents a new data reduction method for sensors used in structural health monitoring application. Our goal is to achieve an effective data reduction...
متن کاملDamage Recognition for Structural Health Monitoring
In the field of structural health monitoring, researchers focus on the design of systems and techniques capable of detecting damage in structures. However, it is difficult to develop robust detection schemes that are invariant to environmental and operational conditions. In this report, we investigate several signal processing and machine learning techniques for developing such robust systems. ...
متن کاملStructural Health Monitoring and Impact Detection Using Neural Networks for Damage Characterization
Detection of damage due to foreign object impact is an important factor in the development of new aerospace vehicles. Acoustic waves generated on impact can be detected using a set of piezoelectric transducers, and the location of impact can be determined by triangulation based on the differences in the arrival time of the waves at each of the sensors. These sensors generate electrical signals ...
