Enig Associates, Inc., a woman-owned, small business providing advanced modeling and simulation capabilities to the DoD and DoE, is proposing an innovative and novel electrical approach, using explosive-driven flux compression generators (FCG) to convert explosive chemical energy to electromagnetic energy with very high current output and superb energy conversion efficiency and then enhance explosive load to augment reaction zone pressure and detonation speed with electromagnetic energy. Electrical conditioning can also be applied to munition casing to control fragmentation and blast pattern and directionality. The proposed program will use Lockheed Martin Missiles & Fire Control (LMMFC) as our Phase I/II subcontractor and is complementary to our DARPA MAHEM Phase 3 program. Both theoretical and computational tools will be utilized in designing an integrated munition with augmented explosion, selectable fragmentation, and controlled blast to provide scalable and adaptive lethal effects against targets.

ENIG, in collaboration with SRI, proposes to develop a modeling methodology with predictive and inferential capabilities to address the challenges of designing body armor to resist realistic multiple impacts from burst fire events. Our toolkit will provide an end-to-end modeling capability, grounded in the statistics of realistic impacts from small-arms fire, which would address the final materials state of a body armor system. ENIG will predict armor performance after an initial impact, predict the location of possible subsequent impacts, and update the materials model with these subsequent impacts. Initially, as a proof-of-concept, ENIG will focus the statistics of realistic burst fire impacts, examine the effect of multiple impacts from a Type IV, armor-piercing rifle threat on a ESAPI consisting of a boron carbide ceramic with a ultra-high molecular weight polyethylene backing. Multiple sets of impact validation studies will be performed to evaluate the ballistic resistance of this system. Methodologies developed here will be used evaluate a variety of small-arms systems, under a range of conditions. The end goal is to provide rigorous probabilistic risk assessments for body armor performance, which would enable better decision-making concerning armor design, materials selection, and requirements generation.

Circuit card assembly (CCA) reliability is dependent on solder joints, which join components to printed circuit boards (PCBs). Board users strive to mitigate risks associated with gold-embrittled solder joints. Enig Associates, Inc. (ENIG), in collaboration with Sandia National Laboratories, proposes to develop a risk-forecasting tool for quantifying the risks associated with gold-embrittled solder joints in electronic assemblies. The team will utilize existing Finite Element (FE) and kinetic Monte Carlo (KMC) tools and modeling approaches to predict the evolution of gold-embrittlement on PCB-level, surface mounted devices. FE models, developed in Comsol Multiphysics and/or ANSYS, will assess stress concentrations in the solder joint adhesion layer, as a function of time and as a result of fabrication and environmental stresses. KMC models will examine the dynamics of intermetallic diffusion in the solid and adhesion layer. Results will be used to estimate bonding area strength in the FE model and to evaluate solder joint performance under transient loads. Approved for Public Release 16-MDA-8620 (1 April 16)

ABSTRACT: Enig Associates, Inc., a small business providing advanced modeling and simulation capabilities to the DoD and DoE, is proposing an innovative and novel electrical approach, using explosive-driven flux compression generators (FCG) to convert explosive chemical energy to electromagnetic energy with very high current output and superb energy conversion efficiency and then Joule heat light metal load in sub millisecond time scale to heat up load from solid metal state to first ionization plasma state going through multi-phase transitions to generate artificial man-made plasma cloud in the ionosphere. The target plasma cloud will be composed of 1025 ion-electron pairs of a few eV temperature propagating initially as hemispherical shell, cylindrical shell, or plasma jet depending on the choice of load material and geometry. The proposed STTR program will have University of Maryland, Space Plasma Physics (SPP) group as our university partner. SPP will perform analytical/computational studies of the generated plasma and plasma cloud interacting with the ionosphere and the geomagnetic field. Both theoretical and computational tools will be utilized in designing an integrated generator device whose form factor fits inside a sounding rocket.; BENEFIT: The developed technology will be tested and demonstrated in the 2nd Phase of the STTR program in a high-altitude magnetized vacuum chamber with detailed diagnostics to validate plasma parameters. A sounding rocket can be utilized to demonstrate the device performance in actual test environments. Once proven successful, the space plasma generator can be used to smooth out ionosphere disturbances to assure reliable communications and navigation in theater, or to provide novel capabilities for RF systems. Advanced plasma generators could also replace civilian systems used as tracers in various upper atmospheric research areas.
