HARDENED GROUND RADOMES FOR SYSTEM SURVIVAL.

Abstract

This nvestigation consists of determining the dynamic response of a thin, uniform-thickness, truncated spherical shell to air-blast induced shock loads. The response analysis includes a failure criterion for determining the vulnerability of this type of structure to nuclear blasts. The structural dynamic characteristics of the radome were represented by the normal mode approach. The mathematical representation of the blast-induced pressure loading was based on published experimental data. A failure criterion based on strain energy considerations is suggested, which, when applied to the dynamic response is indicative of structural failure. Solutions to this mathematical model were obtained from an operational analog computer. The results of this study are promising; however, further investigations considering radomes of different materials and various height-todiameter ratios are required to substantiate the generality of this approach.
