Abstract

This research investigates quantitative evaluation of a flaw near a surface of a structure by using surface waves transmitted and received by electromagnetic acoustic transducers (EMATs). Our numerical simulations of surface waves give us some correlation between flaw depth and receiver signals. Numerical results of the receiver signals agree well with our experimental ones. Thus, surface wave testing by EMATs has good potential of evaluating flaw depth.
