This study investigated applicability of the similarity law proposed by the authors for steel cantilever beams subjected to low velocity impact, by conducting experimental tests and numerical simulations. In a series of tests, a steel ball collided with a steel cantilever beam at velocities of 1-4m/s. Through the comparison of the motion of the steel ball, displacement and strain of the steel cantilever beam between a full-scaled and scaled steel cantilever beams, the proposed similarity law was found to be applicable. Based on the result, the similarity of the impulse was discussed focusing on the role of the coefficient of restitution which important factor for the proposed similarity law.
