The objective of this R & D effort is to develop a computational model that predicts reaction products and effects of reactive materials on the local environment. Release scenarios will include spill, impact and explosion, and the code will provide contamination contours from the release point as… More

For many years, the survivability/vulnerability community has been concerned with the adverse impact of ballistically-induced hydraulic ram on the structural response of aircraft fuel tanks. the navy wishes to develop cost-effectiveness test approaches, fixture designs or panel designs to obtain… More

The objective of this proposal is to formulate an innovative modeling approach for a reactive fragment impact with a target, based on first-order, simplified engineering analysis of key physical and chemical processes. These processes include fragment break-up, energy release rates, energy… More

We propose to develop a near-source model for the release of chemically reacting radionuclides. The model structure is based on an available code for reacting chemicals. The model will include interactive effects of nuclear transformation, chemical reaction, and plume physical motion. Such a… More

"The four major threats of interest in the assessment of target vulnerability and weapon lethality are fragment impacts, blast, hydrodynamic ram and fire. DOD has been working for many years on modeling of the individual effects of each of these threats ontarget damage. The purpose of this project… More

Hydrocodes, CFD codes and aerosolization codes are routinely used to model effects such as shocking of chemical and biological agents inside storage containers subjected to fragments impact, agent expulsion upon container failure and agent dispersion inbunkers. Such codes need accurate properties… More

We propose to perform a series of scoping calculations to determine the propellant and conditions most likely to lead to lethality enhancement under laser heating. For these conditions, we will develop a model to quantify the pressure rise inside the tankdue to chemical reactions. The model will… More

A methodology for determining the failure mode and failure conditions of marine composite structures subjected to blast and ballistic impact will be developed. Analytical expressions characterizing the various failure modes will be derived. Theseexpressions will include the effects of ballistic… More

The key processes of interest are the fragment impact on the storage container, agent expulsion upon container failure, agent dispersion in bunkers and… More

Modeling the fate and transport of CBR agents introduced into water is crucial to predict the vulnerability of current water distribution systems. Current hydraulics models such as EPANet do a reasonably good job of modeling the transport of pollutants in water. Such codes can be used to model the… More

Existing DoD and municipal water supply systems typically lack considerations for counter-terrorism. The motives behind terrorist attacks on utility plants may be denial of service or human casualties. In this study, we focus on the latter, specifically on chemical and biological (CB) agent… More

Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. … More

There is a growing interest in the development of accurate and fast-running target vulnerability models that address the combined effect of fragment and blast on the damage of structures. Here by blast we refer to the dynamic pressure loading due to explosion in either air or water, or to the… More

Because of their high strength to weight ratio, composite materials are being increasingly used to replace metals in current combat vehicles, particularly for armor and structural applications. This trend will continue into the future as requirements become more stringent. Of particular concern… More

BlazeTech proposes a rugged, cost-effective probe which can record the time history of the dynamic pressure in a hostile flow including entrained particulate matter. We will compile a list of flow properties of detonations of interest and perform a detailed study of the expected response of the… More

Weapons directed at enemy stores of chemical and biological agents can cause extreme collateral damage by venting live agents from broken containers into the surrounding area. This is severely hazardous for friendly forces, noncombatants, and the surrounding environment. An Agent Defeat weapon… More

Accidental or intentional contamination of water distribution systems with chemical and biological agents and contaminants can have long-lasting and disastrous consequences. Existing DoD and municipal utility installations currently are not equipped to handle such events. This is due to a lack of… More

We propose to develop scaling relationships for reaction violence in the cook-off of energetic materials such as explosives or propellants.
