Elastic Wave Dispersion in a Cylindrical Rod by a Wide-Band Short-Duration Pulse Technique

Abstract

Dispersion of elastic waves in a cylindrical rod, determined experimentally by means of a wide‐band short‐duration pulse technique, compares well with theoretical curves of the classical theory. This method, compared to previous methods, extends to smaller values the range of the wavelength to diameter ratios which may be studied conveniently. One antisymmetric and two symmetric modes were studied. In addition, waves of a resonant nature associated with the ends of the rod were identified.
