Structural Health Monitoring of Composite Materials Using Piezoelectric Sensors
Structural Health Monitoring (SHM) denotes a system with the ability to detect and interpret adverse " changes " in a structure in order to improve reliability and reduce life-cycle costs. The greatest challenge in designing a SHM system is knowing what " changes " to look for and how to identify them. This paper focuses on the relationship between sensing systems and their ability to detect ch...
متن کاملAerosol-Jet Printed Thin Film Transistors
Thin film transistors are at the heart of integrated circuits. Modern computer processor chips can contain more than 2 billion transistors. Such chips are currently fabricated by expensive lithography processes and fabrication facilities can cost more than one billion US dollars. In a future era of cheap, disposable electronics such cost structures will not be practical. Printed electronics how...
متن کاملStructural Health Monitoring for Composite Materials
A composite material can be defined as a combination of two or more distinct materials at a macroscopic level to attain new properties that can’t be achieved by those of individual components acting alone. Different from metallic alloys, each material keeps its own chemical, physical and mechanical properties [1]. Composite materials have reinforcing and matrix phases. The reinforcing phase wit...
متن کاملMultifunctional Vehicle Structural Health Monitoring Opportunities with Piezoelectric Wafer Active Sensors
The capability of embedded piezoelectric wafer active sensors (PWAS) to perform in-situ nondestructive evaluation (NDE) is explored. Laboratory tests are used to prove that PWAS can satisfactorily perform Lamb wave transmission and reception. Subsequently, crack detection in an aircraft panel with the pulseecho method is illustrated. For large area scanning, a PWAS phased array is used to creat...
متن کاملPiezoelectric Wafer Active Sensors for Structural Health Monitoring of Composite Structures Using Tuned Guided Waves
Piezoelectric wafer active sensors (PWAS) are lightweight and inexpensive transducers that enable a large class of structural health monitoring (SHM) applications such as: (a) embedded guided wave ultrasonics, i.e., pitch-catch, pulse-echo, phased arrays; (b) highfrequency modal sensing, i.e., the electro-mechanical (E=M) impedance method; and (c) passive detection (acoustic emission and impact...
