APPLICATION OF THE HERTZ CONTACT LAW TO PROBLEMS OF IMPACT IN PLATES

Abstract

An experimental and theoretical investigation of transverse impact produced by the collision of strikers with steel square plates with and without covering was performed. The purpose of this report is to determine the validity of the static treatment of pressure on thin plates for the dynamic cases of intermediate impact velocities, the use of the Hertz law for the contact of an elastic projectile (steel) on elastic (steel), viscoelastic (Adiprene), and plastic (Lexan) bodies, and the use of viscoelastic and plastic materials as shock mitigators.
