A previous article [Moffettetal., J. Acoust. Soc. Am.89, 1448–1455 (1991)], comparing the radiated‐power limitations of Terfenol‐D and PZT‐4, is revisited. When the power at resonance is stress‐limited (as is the case for high mechanical quality factorQ), the maximum allowable stress amplitudeTmaxis the compressive prestress value, so that tension in the Terfenol‐D is avoided. When this value is chosen forTmax, rather than the smallerTmax’s of the previous article, Terfenol‐D is shown to be superior to PZT‐4 in power capability at all values of the quality factorQ.
