Abstract
The paper reviews the recent applications of piezoelectric materials in structural health monitoring and repair conducted by the authors. First, commonly used piezoelectric materials in structural health monitoring and structure repair are introduced. The analysis of plain piezoelectric sensors and actuators and interdigital transducer and their applications in beam, plate and pipe structures for damage detection are reviewed in detail. Second, an overview is presented on the recent advances in the applications of piezoelectric materials in structural repair. In addition, the basic principle and the current development of the technique are examined.
Highlights
The assessment of the performance of structures in terms of ultimate and serviceability limit state, durability and catastrophic failure has always been an important issue
Many practical and robust non-destructive evaluation (NDE) techniques for structural health monitoring at the element level have been developed based on wave propagation signals [1,2,3]
The analysis of plain piezoelectric sensors and actuators and interdigital transducer and their applications in beam, plate and pipe structures for damage detection are presented in Sections 3 and 4, respectively
Summary
The assessment of the performance of structures in terms of ultimate and serviceability limit state, durability and catastrophic failure has always been an important issue. Many practical and robust non-destructive evaluation (NDE) techniques for structural health monitoring at the element level have been developed based on wave propagation signals [1,2,3]. The review highlighted the need for more effective repair methods using smart materials [34,35,36] to be developed, since the strains and stresses in areas surrounding the damaged domain may cause additional damage, which results in severe reduction in the service life of the entire structure. The analysis of plain piezoelectric sensors and actuators and interdigital transducer and their applications in beam, plate and pipe structures for damage detection are presented in Sections 3 and 4, respectively.
