摘要

The emerging field of embedded ultrasonic NDE has the potential of producing fundamental changes in structural health monitoring, damage detection, and nondestructive evaluation by using small inexpensive and unobtrusive PWAS transducers that are permanently attached to the structure and can be interrogated at will. Unlike conventional ultrasonic transducers, PWAS are low power non-resonant devices with broadband capabilities. PWAS are about the only transducers that can be embedded in large numbers in the structure without an exorbitant cost and weight penalty. Though the PWAS capabilities have been validated experimentally, the modeling of the PWAS behavior is still being developed. Fundamental aspects of the Lamb-wave interaction between PWAS and host structure during structural health monitoring need to be studied and understood.
