Composite Material Modeling for Blast Protection
Abstract
The USMC/USA has been successfully developing crew/vehicle protection kits (CPK) to provide increased crew survivability of tactical wheeled vehicles subject to mine blast. However, these CPK's are currently based on a conventional steel/aluminum construction and are close to 1/2 ton in weight. As may be expected, there are payload and mobility penalties associated with the utilization of these devices in the field. Use of lightweight composite material elements presents an opportunity for significant weight savings. It may be readily seen that efficient composite design requires an integrated approach whereby, the material selection, material construction, and response of the structure are all considered concurrently. In general, hydrocodes, however, have been developed mainly for isotropic structures. Phase I of this study has demonstrated that dynamic structural It may be readily seen that efficient composite design requires an integrated approach whereby, the material selection, material construction, and response of the structure are all considered concurrently. In general, hydrocodes, however, have been developed mainly for isotropic structures. Phase I of this study has demonstrated that dynamic structural analysis with the presence of shock waves can be accomplished by the integration of composite material models with a hydrocode. Further research efforts are needed to fully implement these composite material models with the hydrocode and validate the modeling capability for USMC composite structures.
