Capabilities

Warhead Design

  • Novel concepts for explosively- and magnetically-formed shaped charges, self-forging penetrators, and aimable fragmenting warheads.
  • Warhead concepting and design to provide multiple mode and combined effects lethality for soft and hard target applications.
  • Generation of lethal kinetic energy mass using electromagnetic energy sources such as flux compression generators.

High Pressure Behavior of Materials

  • Predictions from first principles of the high-pressure static and dynamic behavior of metals, polymers, porous materials, explosives, and reactive materials.
  • Equations of state of metals, polymers, porous materials, explosives, and non-explosive reactive materials.

Thermal Ignition and Combustion

  • Thermal ignition/explosion phenomena related to unsteady and steady-state heating of energetic materials with reactant consumption and/or non-uniform boundary conditions, theoretical derivation of criticality conditions, and propellant hazards predictions.
  • Combustion theory, including ignition exchange criteria for flames on combustible solid surfaces, steady-state laminar flames, and time-dependent flame stability.

Nano-Materials Design and Modeling

  • Ab initio and density functional quantum chemical simulations to determine the structural effects of nano-inclusions.
  • Time-dependent density functional theory to model interactions between matter and strong laser pulses and to describe confinement-induced optical response shift in quantum wells.
  • Semi-classical analyses to probe the cross-over between quantum and classical regimes, with techniques which include Molecular Dynamics (MD) and kinetic Monte Carlo simulations.

Electromagnetic Theory

  • Propagation of electromagnetic waves and interactions with atomic and molecular systems.
  • Magnetohydrodynamic devices.
  • Self-contained portable flux compression generator systems.
  • Explosive generator designs with coupled load design for unique electromagnetic and mechanical lethal effects.
  • Electrodynamics and plasma chemistry in air and other gases focused on the transport properties of discharges, the power flow in non-thermal plasma (NTP) devices, as well as gas breakdown models.

Explosives, Explosions, and Applications

  • Computational fluid dynamics applied to detonation and explosion problems.
  • Detonation propagation and failure diameter theory.
  • Underwater blast waves and explosion bubble phenomena.
  • Properties of aluminized explosives.
  • Detonation phenomenology applied to warhead concepts.
  • Physical and/or mathematical modeling of initiation/ignition of porous, heterogeneous, energetic materials through interaction of shock waves with materials microstructure to create thermal “hot spots”.
  • Phenomenological modeling of growth to detonation in insensitive explosives with large reaction zones.
  • Mathematical models for the ignition of hot spots and subsequent hot spot-initiated reaction for shock-to-detonation transition (SOT) in heterogeneous explosives.
