The Elastic Plastic Response of Long Slender Rods Subjected to Impulsive Type Loadings

Abstract

Experimental and analytical results are presented for the elastic plastic deformation of a slender rod subjected to impulsive loading that occurs during the impact of a rod against a rigid plate. Particular emphasis is given to the lateral or flexure buckling mode shapes that occur during the impact. The transient response and resulting deformation were recorded with the aid of high speed photography and flash X-rays. A frame-by-frame record of the impact phenomena gives the displacement of a particle on the rod and the plastic wave propagation position. Also presented are three distinct failure modes that result, dependent primarily upon impact geometry.
