Experimental Study on the Axial Impact of a Bar, Accompanied by Lateral Deformation : One End Built-in and the Other Simply Supported

Abstract

By experimenting on bars subjected to an axial impact by a rigid mass, the author has investigated effects which the initial curvature of a bar, the ratio of the rigid mass to the bar and the velocity of the impact that produces the axial stress or the lateral deformation of the bar. The larger are the value of initial curvature, the ratio of the mass to the bar and the velocity of impact, the larger the value of lateral deformation of the bar is, and when this deformation becomes larger than a certain value, the mass runs against the bar twice or more before one impact is over.
