Measurements of Dynamic Stress and Strain Components in Targets Struck by Penetrators

Abstract

Stress and strain profiles have been recorded in targets impacted by long-rod kinetic-energy projectiles. Stress gauge records were strongly influenced by the strain field in the target, so compensating strain measurements were used to derive the correct stress profile. Strain-compensated stress gauges in the projectile path measured stress which increased to a value that remained nearly constant until penetration neared the gauge. This constant stress was close to the value of the Hugoniot Elastic Limit of the target material.
