Abstract
Advances in non-destructive testing and evaluation has given rise to the use of embedded structural health monitoring (SHM) for space structures. Space venturing companies and governments are looking to utilize the SHM technology to improve their missions and capabilities of future space vehicles. The need for modeling and analyzing data for SHM purposes increases with the increased interest in the field. With many different entities pursuing many different avenues to perform SHM it is important to create tools that can guide practical SHM applications. Piezoelectric transducers have seen much use in the field due to their ability to perform as sensors and actuators. The transducers can be used as active components to determine damage to a structure using electro-mechanical impedance methods. The research presented insights into creating tools for real-time electro-mechanical impedance SHM. The electro-mechanical impedance tool investigates the use of a circuit simulation to model the electro-mechanical response of a piezoelectric and a structure. Various elements of the circuit modeling are discussed and practical applications to modeling both sensor and structure are given.
