Abstract : The ultrasonic harmonic generation technique previously used to measure third-order elastic (TOE) constants of crystals of cubic symmetry has been extended to measurement of crystals of trigonal symmetry. The theory for nonpiezoeletric trigonal crystals of J. Phillip has been combined with the piezoelectric theory of McMahon to determine the effective TOE constants in a piezoelectric solid, and a correction has been made to McMahon's expression.
