Penetration of a Rigid Rod into a Thick Steel Plate at Elevated Velocities

Abstract

Results of studies on the effect of impact velocities and shapes of the head face of a rigid rod on its behavior upon penetration into a thick plate from mild low-carbon steel at velocities of up to 600 m/s are presented. Experimental relations between penetration depths and impact velocities were obtained for rods with conical and hemispherical head faces. A simple analytical description of the process allowing for the effect of viscous resistance at the initial stage of the rod's penetration into the plate was proposed.
