摘要：

Experimental data are presented that show the feasibility of producing and detecting longitudinal, torsional, and flexural wave modes in a steel rod using sensors based on the Joule nod Villari magnetostrictive effects. By changing the sensor configuration nod the distribution of the biasing magnetic field applied to the rod, single, or multiple wave modes can be simultaneously generated and detected. The magnetostrictive sensors provide a very simple means of experimentally investigating the properties of wave propagation in a frequency range up to a few 100 kHz.
