• The purpose of this paper is to examine not only qualitatively but also quantitatively the influence of a rise time of longitudinal impact on the propagation of elastic waves in a bar. The adequacy of application of Love's theory for the propagation of longitudinal elastic waves to this problem is discussed by means of the simultaneous measuring of both axial and radial strains at the same stations along a bar. Theoretical results based on the Love theory predicted that, as the rise time of impact velocity increases, the effect of lateral inertia on longitudinal waves decreases and then the oscillatory wakes of it become negligibly small. Experimental results for a steel bar agreed well with the theoretical results. Moreover, as an example of appication, the experimental measurement of the dynamic yield stress by using a stress bar was analyzed.
