An asymmetric mine-soil-structure interaction problem with two competing plate thicknesses was modeled using a hydrodynamic code. The plate acts as a momentum trap for a vertical impulse test facility proposed at the Aberdeen Proving Ground. The model allows simulation of complex asymmetric explosive-soil-structure interaction effects and generates loading and response of the plate due to varying center line offset, stand-off, depth of soil overburden and explosive contents. The objective is to select a minimally thick plate which must survive the interaction without any significant residual permanent deformation.
