A STUDY OF HERTZIAN IMPACT ON GLASS AND ALUMINUM HEMISPHERICAL SHELLS WITH MITIGATOR,

Abstract

Hertzian impact theory and a solution published by E. Reissner for an unrestrained shallow spherical shell are used to find total stress on the inner surface of a hemispherical shell covered by a viscoelastic mitigator. From data obtained by experimental means and published references, it is concluded that Hertzian impact theory is valid for certain type shells as well as solid bodies and that a mitigator will effectively reduce stresses in an impacted shell.
