This article deals with damage detection process under varying temperature. Carbon fibre–reinforced polymer samples are investigated using electromechanical impedance method. In the article, influence of changing temperature on resistance in electromechanical impedance is investigated. Authors propose new approach for compensation of temperature influence on damage detection. Damage detection is based on root mean square deviation index. Due to strong damping of utilized composite material, low-frequency range is utilized in this research. Real part of electromechanical impedance is measured for frequency band 1–20 kHz. Damage is in the form of artificially made delamination with different sizes. Authors also discuss the problem of influence of structure’s boundary condition on low-frequency measurements. In the research, scanning laser vibrometry for guided wave propagation method is utilized for visualization of the introduced delamination.

Impedance Technique

Piezoelectric transducers are widely used in many nondestructive methods for damage detection in structural health monitoring applications. Among the various methods for detecting damage, the electromechanical impedance technique is known for using thin and small piezoelectric ceramics operating simultaneously as actuators and sensors. The basic method of installing these piezoelectric ceramics in the host structure is using a high-stiffness adhesive such as epoxy or cyanoacrylate glue. However, some studies have proposed alternative methods of transducer mounting, therein aiming to reuse the transducer or allowing for the monitoring of structures under adverse conditions under which the direct installation of the sensor would not be possible. Thus, the objective of this study is to analyze and compare the performance of three main mounting methods for metal structures for applications based on the electromechanical impedance technique: magnetic mounting, metal-wire-based mounting, and conventional mounting using adhesives. Tests were conducted on aluminum beams, and the performances of the three transducer mounting methods were compared using basic damage indices and the pencil-lead-break test. The experimental results indicate that the mounting method has a significant effect on the frequency response and sensitivity for damage detection.

Set Up

This work is devoted to the use of the electromechanical impedance method for the damage detection in a riveted aircraft element. In the first part of the paper a theoretical background of the impedance-based damage detection technique is made. Next, the description of the utilised experimental set-up is described. Then, an application of the method used to detect damage in a wing sheathing of a turboprop training aircraft is presented. A damage scheme incorporating multiple notches through the selected rivets is considered. Finally, the suitability of the described method to distinguish close and far field damages is discussed.

The Impact

The sensitivity of the electromechanical impedance to structural damage under varying temperature is investigated in this paper. An approach based on maximizing cross-correlation coefficients is used to compensate temperature effects. The experiments are carried out on an air plane conform carbon fiber reinforced plastic (CFRP) panel (500mm x 500mm x 5mm) instrumented with 26 piezoelectric transducers of two different sizes. In a first step, the panel is stepwise subjected to temperatures between-50 °C and 100 °C. The influence of varying temperatures on the measured impedances and the capability of the temperature compensation approach are analyzed. Next, the sensitivity to a 200 J impact damage is analyzed and it is set in relation to the influence of a temperature change. It becomes apparent the impact of the transducer size and location on the quality of the damage detection. The results further indicate a significant influence of temperature on the measured spectra. However, applying the temperature compensation algorithm can reduce the temperature effect at the same time increasing the transducer sensitivity within its measuring area. The paper concludes with a discussion about the trade-off between the sensing area, where damage should be detected, and the temperature range, in which damage within this area can reliably be detected.
