Baseline-free Imaging Method based on New PZT Sensor Arrangements (2009, methodology): “For an idealized and simplified plate model, when an arbitrary PZT element (P0) is used as an actuator, the response voltage at a PZT sensor Pi can be represented as follows (Wang et al., 2004; Park et al., 2007):”
Single Mode Tuning Effects on Lamb Wave Time Reversal with Piezoelectric Wafer Active Sensors for Structural Health Monitoring (2007, methodology): “As a baseline free SHM technique, Lamb wave time reversal method has experimentally demonstrated its ability to instantaneously detect certain types of damages in thinwall structure without using pristine baseline data [8, 17].”
Damage Detection in Composite Plates by Using an Enhanced Time Reversal Method (2007, methodology): “By developing a unique combination of a narrowband excitation signal and wavelet-based signal processing techniques, the authors demonstrated previously that the original input waveform could be successfully reconstructed in a composite plate through the enhanced time reversal method (Park et al. 20”
Understanding a time reversal process in Lamb wave propagation (2009, methodology): “In reality, the time reversal operator is frequency dependent for Lamb waves [10,32] because signal components at different frequencies travel at different speeds and varying attenuation rates.”
Embedded non-destructive evaluation for structural health monitoring, damage detection, and failure prevention (2005, methodology): “Sohn et al. (2004a) and Park et al. (2004) used the time reversal method to detect damage in composite panels.”
Parameter Estimation of the Generalized Extreme Value Distribution for Structural Health Monitoring (2005, background): “According to the time reversal concept, an input signal can be reconstructed at an excitation point if an output signal recorded at the other point is re-emitted to the original excitation point after being reversed in a time domain [17,18].”
Impact detection in anisotropic materials using a time reversal approach (2012, methodology): “Time reversal process has also been widely used in medical applications and non-destructive evaluation (NDE) techniques like pulse-echo methods for damage detection in pipes [9] and in both aluminium [22, 25] and quasi-isotropic composite [15] structures.”
