Abstract An electromagnetic-acoustic transducer (EMAT) system was used in conjunction with a “sampled” CW signal-processing method to generate, receive, and process longitudinal and shear waves in thin steel sheets. Using the system, swept-frequency measurements were made up to 7.5 MHz. To relate the measurements to sheet steel formability, a dimensionless frequency ratio,K, was computed from the resonant frequencies. From theoretical considerations,K should be related to a measure of steel sheet formability, $$\bar r$$ . This parameter is traditionally measured by plastically deforming uniaxial tension specimens. Good correlation was found betweenK and $$\bar r$$ for a set of steel sheet representative of those typically used to produce automobile body parts.
