Abstract
The described method allows the determination of velocity and attenuation variations introduced by low frequency alternating stresses and electric fields. Uniaxial stress is produced with a high load piezoelectric actuator and controlled with a strain gauge bridge. A modified impulse echo overlap system with a computer controlled sampling oscilloscope permits the measurement of very small effects. Results for Potassium Dihydrogen Phosphate (KDP) near the phase transition at 123 K are presented and discussed.
