Rotated Elastic and Piezoelectric Coefficients of Ammonium Dihydrogen Phosphate

Abstract

By applying transformation equations to Mason's experimental results, the elastic and piezoelectric coefficients of ammonium dihydrogen phosphate (APD) are computed for separate rotations about the crystallographic axes. Young's modulus for the long bar is similarly treated. Expressions are derived for the Mason D' piezoelectric coefficient and for k, the electromechanical coupling, of the Z-cut long bar.
