Experimental and numerical analysis of piezoelectric active repair of edge-cracked plate

Abstract

This article proposes an alternative model for active repair for an edge-cracked plate with adhesively bonded piezoelectric actuator. It computes the Mode-I stress intensity factor (SIF) produced by the piezoelectric actuators using appropriate derived geometrical weight functions. Furthermore, this article presents an experimental study to verify the proposed analytical model and the finite element analysis using ANSYS software. Therefore, the analytical, finite element and experimental results for Mode-I opening of the crack conditions are demonstrated. Parametric analysis to understand the influence and to study the efficiency of the piezoelectric actuator on mitigation of the Mode-I SIF was conducted. The obtained analytical solution is applicable in the calculation of Mode-I SIF with reasonable accuracy. The result indicated that the maximum reduction of SIF is achieved with the application of high external voltage and thin thickness actuator. The relative errors of the analytical model and the experimental results are less than 10% in all the cases studied in this article.

A Systematic Review of Piezoelectric Materials and Energy Harvesters for Industrial Applications

“…The ideas were developed to produce compression/tension stress around the damaged area along with the width of the piezoelectric actuator. The authors stated that increasing the piezoelectric voltage will result in a decrease of fracture parameters such as stress intensity factor [ 101 ] and stress concentration factor [ 102 ], but the supplied voltage increase was only up to 150 V in their studies [ 100 , 103 , 104 ] due to limited voltage. The piezoelectric actuators have the advantage to control/repair the damaged aerospace structures, but it has a limitation of the voltage.…”

Review of Piezoelectric Actuator Applications in Damaged Structures: Challenges and Opportunities

“…Sarangi et al 115 experimentally verified the optimal strain gauge locations and their importance in the accurate determination of mode I SIF using daily and Sanford’s single-strain gauge training (DS technique). Abuzaid et al 116 conducted the experimental work for the repair of the damaged plate (edge-cracked) with a bonded PZT actuator. To obtain the SIF for a mode I crack propagation, strain gauges were used.…”

“…In the year 2017, a few studies were found on the active repair of metallic structures. For instance, Abuzaid et al ,,, used PZT patches for the repair of the plate through an experimental, numerical, and analytical method since it can be developed for metallic and nonmetallic materials of repair. However, in the next level of study, it can be possible to consider tubes/pipes or other types of structures for active repair because this type of structural repair has been found in passive repair .…”

A Review of Piezoelectric Material-Based Structural Control and Health Monitoring Techniques for Engineering Structures: Challenges and Opportunities

“…The ideas developed to produce stress (compression/tension) on the stress distribution around the hole and along with the width of the damaged plate by the piezoelectric actuator. The methodologies were adopted via experimental work for an edge-cracked plate [92] and edge-and center-cracked analytical modeling using the crack-closer method [91] and weight function method [92] and numerical simulation via ANSYS simulation [92,93]. To determine SIF for the center-cracked plate, concentrated on the location of the piezoelectric patch on a cracked plate with respect to the dimension by changing the patch location and thickness of adhesive layers.…”
