Advanced Analytical Models for Innovative Vehicle Composite Structures against Land Explosives

A Multi-level and Multi-scenario Blast Simulation and Design System

Objective of this research is to develop design concepts that can be used in the Army's FCS and FTTS to protect vehicles and occupants against blasts from various explosives. We propose to use advanced design methodologies, associated software modules, and physical prototypes for this innovative composite structure. We will develop a multi-level and multi-scenario blast simulation and design system integrating three new major technologies originally developed at MKP Inc., namely an advanced mine-soil-composite interaction model, an award-winning design methodology, called Function-Oriented Material Design (FOMD), and a novel patent-pending composite material concept, called Biomimetic Tendon-Reinforced (BTR) material.

The developed system will enable the prediction, designing, and prototyping of composite structures for a wide range of damage scenarios in various blast events, ranging from vehicle rollover, localized structural failure, blast fragment penetration, to crew injuries. The different levels of simulation and design capabilities will be implemented in an integrated software system called FOMD-Blast with well-defined graphic user interfaces as detailed in the proposal. A novel blast-protective composite concept, BTR-Bl, is also proposed in this program as a proof of concept for the technologies developed. The major design goal is to meet the blast protection requirements with other essential features, such as light-weight, flexibility, maintainability, and reduced life-cycle cost. This BTR-Bl concept will be optimized using the simulation and design capabilities developed in this program, and will be fabricated for further performance evaluation.

The completed software developed in this program could be expanded for use over a broad range of military and civilian security applications where the modeling and design for protecting against landmines, IEDs, or other explosives might be needed. Within the Army these might include, but are not limited to, ground vehicle design, countermine equipment, EOD (Explosive Ordnance Disposal) issues, and personal protection issues. Within civilian security applications, this software might be utilized in a variety of homeland defense technology development as well as police bomb squad technology development.
