Implication

Simulation study demonstrates damage localization in isotropic plates using piezoelectric phased array filters, indicating a directional approach for structural monitoring.

Key Points

To evaluate the capability of directional piezoelectric phased array filters to detect and locate structural damage in isotropic plates using wave propagation.
Interrogated an isotropic plate with simulated damage using low-frequency Lamb waves.
Configured piezoelectric sensor arrays as directional filters to sweep and evaluate transient wave responses across multiple angles.
Damage presence was identifiable via measurable shifts in the plate's transient wave propagation response.
Directional filtering of reflected incident wavefronts enabled the spatial determination and localization of the damaged plate region.
