Rupture as a Function of Deformation in Flat Plates Exposed to HE Mine Blast

Abstract

This report addresses the vulnerability of armored vehicles and possible injury of their occupants to HE mine blast loading. Specifically reported are the results of literary research in the following two areas: the value (height) of flat plate deformation that can be associated with plate rupture, and the hazard to vehicle occupants of the vertical motion of the floor armor, especially the elastic (temporary) deflection. Values are shown for the threshold of plate rupture as a function of deformation for various plate thicknesses. Vertical, elastic-phase, deflections of one or two inches for large, open, floor areas are predicted, for non-rupturing blast mine loading. Occupant injuries are likely here, and shock isolation references are briefly discussed.
