Abstract

The velocities at which elastic vibrational waves propagate in an aluminum cantilever beam are studied analytically, numerically, and experimentally. In order to predict these propagation velocities, both beam theory and modal analysis have been employed. Experimental results are compared with theoretical results in order to determine the degree of correlation. This comparison shows that the holographically observed velocities concur with the analytically determined velocities. Problems with the particular numerical approach employed in this work are presented and discussed.
