Rapid localization of multiple damages and non-intrusive imaging of these damages can
greatly help in reducing the inspection time for guided wave based NDE and in integrated
SHM. A circular array of sensor-actuator network was employed for scanning a panel type
structure for quantitative damage detection besides nonintrusive imaging with the help of the
available reduced number of measurements and a mathematical model. This method
employs Lamb waves with a narrow frequency band of excitation. What is advantageous in …
