Journal ArticleDOI
Detection of cracks in plates using piezo-actuated Lamb waves
TL;DR: In this article, a comprehensive methodology for locating and determining the extent of linear cracks in homogeneous plates based on the time-of-flight analysis of Lamb wave propagation is proposed.
Journal ArticleDOI
Vibration control of smart piezoelectric composite plates
TL;DR: In this paper, the effect of the stretching-bending coupling of the piezoelectric sensor/actuator pairs on the system stability of smart composite plates is investigated.
Journal ArticleDOI
Love waves in piezoelectric coupled solid media
TL;DR: In this paper, the dispersive characteristics and the mode shapes of the deflection and the electric potential in the thickness direction of the piezoelectric layer are theoretically derived, and numerical simulations show that the phase velocities initiate at the shear wave velocity of the host medium and tend towards the Bleustein-Gulyayev surface wave velocity at high wavenumbers for the first mode.
Journal ArticleDOI
Vibration Control of Composite Plates via Optimal Placement of Piezoelectric Patches
TL;DR: In this article, a simple optimal placement strategy of piezoelectric sensor/actuator pairs for vibration control of laminated composite plate is presented, where the active damping effect under a classical control framework is maximized using the finite element approach.
