• When applying the results of a model study to practical problems, it is convenient to know the relation of similarity in them. We experience an impact behavior as shown in a contact of cam and cam straddle, more space after punctuation arc spot welding, etc. This paper studies mechanical similarity in the collision between two round bars or a round bar and periphery of a circular disk, which are of various dimensions and material constants. It is important that the similarity of stress and the equation of motion are valid for the dimensions, material constants of the member, and the time. Supposing the dynamic similarity, we could investigate the response to the use of the material which is stable to the impact, instead of, for example, titanium of firing caused by heat storage resulting from rapid deformation, and valuable materials which need not be subjected to an unknown impact load.
