This paper is concerned with the wave propagation in a sandwich structure bar, the free end of which is struck in the direction of the length by a rigid hammer. The bond layer in subjected to a dynamic shearing strain by the resulting elastic waves, which are generated in both the facing and the core by the longitudinal impact. In taking note of the fact that the magnitudes of the axial strains in the facing and the core as well as the shearing strain in the bond layer depend greatly on the modulus of rigidity of the bond layer, the modulus of rigidity of the bond layer was estimated by comparing the calculated values of the ratio of the axial strain in the core ot that in the facing with experimental values. As a result, the values of the modulus of rigidity estimated by this method for two different sandwith structures bars almost agreed.
