EQUATIONS FOR COMPUTING ELASTIC CONSTANTS FROM FLEXURAL AND TORSIONAL RESONANT FREQUENCIES OF VIBRATION OF PRISMS AND CYLINDERS

EQUATIONS ARE GIVEN FOR COMPUTING YOUNG'S MODULUS AND THE SHEAR MODULUS FROM FLEXURAL AND TORSIONAL RESONANT FREQUENCIES, RESPECTIVELY. GRAPHS ARE GIVEN FROM WHICH THE SIZE AND SHAPE FACTOR C IN THE EQUATION FOR YOUNG'S MODULUS AND GOENS' CORRECTION FACTOR T ARE READILY DETERMINED. AN EQUATION IS GIVEN FOR OBTAINING POISSON'S RATIO FROM THE FLEXURAL AND TORSIONAL RESONANT FREQUENCIES, AND THE LIMITATIONS OF THE EQUATION ARE DISCUSSED. /PCA/
