The fracture strength of the adhesive butt joint of a round steel bar bonded by cyano-acrylate for tensile stress waves and alternating waves was measured experimentally. The tensile stress wave initiates in the round bar with the adhesive butt joint as the anvil attached at the end of the bar is struck by the dropping a circular cylinder. The alternating stress waves, which change from compressive to tensile, repeatedly propagate in the longer bar, as two bars of unequal length coaxially collide into each other. The location of the joint is designed to agree with the position at which the intermittent or serial alternating stress waves are observed. The fracture strength of the adhesive decreases as the acting period of waves increases. The fracture strength for intermittent waves is larger than for serial waves. The dynamic fracture strength was compared with the result for static fracture strength.
