Conjunction of two ultrasonic NDT methods in SHM system
Original language description
The main goal of structural health monitoring (SHM) is to prevent failures and limiting states of the structure. Material and structural changes, resulting from aging and extreme events, can be reliably recognized by conjunction of various NDT/NDE methods. Selection of suitable methods is influenced as by technical parameters and economical indicators as well. Necessary conditions are also demands on full automation, including data transfer, processing, storage, and evaluation. Possibilities of two ultrasonic NDT methods combination, considered as a part of SHM systems are discussed in this paper. The first method is acoustic emission (AE), which enables real-time localization of structural damage initiation under operational stimulation conditions. The second method is Nonlinear Elastic Wave Spectroscopy (NEWS), which can be used without structure stimulation. A good correspondence of defective zones revealed by both methods/ is illustrated on fatigue damage of an aircraft part.
