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