THE MECHANICAL IMPEDANCE ANALYSIS METHOD OF NONDESTRUCTIVE TESTING (A REVIEW)
Source abstract
Abstract
The mechanical impedance analysis (MIA) method is nowadays widely used for detecting debonds in multilayer structures made of advanced composites, metals and other materials in different combinations, delaminations in plastics and some other defects. Testing is carried out with one-sided access, no liquid couplant is required. In tested objects bending waves of sonic and low ultrasonic frequencies are excited. For about 12 years the MIA method has been used in Russia only. But since 1973 the MIA flaw detectors have been produced in the West too, first by INSPECTION INSTRUMENTS (U.K.) and then by STAVELEY. This review article gives brief systematic information about the up-to-date state of MIA method, its basic principles, types of probes and their characteristics, capabilities and applications. A newly developed pulse version of the MIA method is described, which enables the design of portable flaw detectors, especially suitable for in-service testing.
