SYSTEMS AND METHODS FOR DAMAGE DETECTION IN PLATE-LIKE STRUCTURES USING GUIDED WAVE PHASED ARRAYS

摘要

A method for ultrasonic guided wave defect detection in a plate-like structure is disclosed. The method includes driving a plurality of transducers to cause guided waves to be transmitted in the plate in a predetermined direction or focused at a predetermined focal point, receiving at least one reflected guided wave signal, and processing the at least one reflected guided wave signal to identify a location of at least one possible defect in the plate-like structure. Defect detection data including the location of the at least one possible defect in the plate-like structure is stored in a machine readable storage medium.
