Design of a piezoelectric-based structural health monitoring system for damage detection in composite materials
Cost-effective and reliable damage detection is critical for the utilization of composite materials. This paper presents the conclusions of an experimental and analytical survey of candidate methods for in-situ damage detection in composite structures. Experimental results are presented for the application of modal analysis and Lamb wave techniques to quasi-isotropic graphite/epoxy test specime...
متن کاملFinite-dimensional piezoelectric transducer modeling for guided wave based structural health monitoring
Among the various schemes being considered for structural health monitoring (SHM), guided wave (GW) testing in particular has shown great promise. While GW testing using hand-held transducers for non-destructive evaluation (NDE) is a well established technology, GW testing for SHM using surface-bonded/embedded piezoelectric wafer transducers (piezos) is relatively in its formative years. Little...
متن کاملStructural 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 کاملPiezoelectric Transducer Diagnostics via Linear Reciprocity for Guided Wave Structural Health Monitoring
Guided waves using spatially distributed piezoelectric transducers are being applied to many structural health monitoring applications. These surface-mounted transducers, which are typically lead zirconate titanate, are generally assumed to be both undamaged and properly bonded to the host structure during usage. However, this assumption may not be valid, particularly after long-term operation ...
متن کاملDevelopment of a Flexible Lead-Free Piezoelectric Transducer for Health Monitoring in the Space Environment
In this work we report on the fabrication process for the development of a flexible piezopolymeric transducer for health monitoring applications, based on lead-free, piezoelectric zinc oxide (ZnO) thin films. All the selected materials are compatible with the space environment and were deposited by the RF magnetron sputtering technique at room temperature, in view of preserving the total flexib...
