The current Phase II program is focused on refining, verifying and validating of an affordable test method to extract local crack growth data for cracks propagating through Microtexture Regions (MTRs) in titanium material. Per the solicitation, emphasis will be given to near-threshold cold dwell crack growth conditions where the crack tip constraint may be considered to be plane strain. Under thes ...

We propose to develop a set of multiscale modeling tools for structural reactive materials (SRMs) that explicitly treat microscale, mesoscale and macroscale coupling of mechanical response, thermal properties and chemical reactions. At the macroscale, a combined material point method (MPM, solid)/Eulerian (ICE, fluid) methodology, MPM-ICE, will be employed to investigate the behavior of select int ...

The result of this project will be the integration of the advanced, high-fidelity physics-based hydrocode, EPIC, into the DoDs Modular Effectiveness Vulnerability Assessment (MEVA) code. This will be accomplished by integrating a flexible, open-source, application integration infrastructure called IMPACT, developed and supported by Illinois Rocstar, into Endgame Framework.To address the need for h ...

The state-of-the-art in infrared scene projection uses micro-machined resistor arrays. These arrays have limited frame-rate, dynamic range, and can be cost prohibitive as the array size increases. Alternative technologies are required. The most promising is infrared light emitting diodes (IR LED) based on InAs/GaSb type-II superlattices (T2SL) or W-Quantum Wells, with the ability to tune the bandg ...

Achieving desired bondline temperatures is critical to ensuring proper wetting, flow and cure when repairing composite structures. Under this multi-phase SBIR project a novel method for measuring/managing cure temperature in the bondline is being pursued based on patented amorphous microwire temperature sensors that are placed permanently within the bondline and read remotely via low-frequency ele ...

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project will focus on the design of the first completely automated radio frequency ablation (RFA) system for breast tissue. Of the approximately 200,000 breast cancer patients in the US who elect lumpectomy annually, over 20% must undergo re-operation due to lack of clear margins. Furthermore, many b ...

This Small Business Innovation Research (SBIR) Phase II project will accelerate the adoption of data intensive precision agriculture, increasing yields while decreasing farm inputs such as fertilizers and pesticides. This project removes the software bottleneck (time and labor) in processing large aerial surveys taken by Unmanned Aerial Systems, enabling a cost-effective and timely process to deli ...

MicroLink Devicesproposes to develop an ultra-high efficiency, radiation-hard, six-junction solar cell for application to Air Force space missions. The proposed technology will comprise lattice-matched subcells grown on InP and GaAs substrates that are mechanically attached in a monolithic structure to achieve 1-sun AM0 efficiency in excess of 40%. To render the solar cell cost-efficient, epitaxia ...

We propose to investigate and implement novel designs to improve manufacturability of Traveling Wave Tubes (TWTs) for VW/E-band high data rate communications. High power amplification is needed with improved efficiency to reduce operation power and improve reliability.TWT design and development becomes difficult at V/W-bands due to very small circuit dimensions at these higher frequencies. Coupled ...

ABSTRACT: Conductive Composites has developed lightweight materials that provide high levels of conductivity and electromagnetic (EM) shielding for composite and advanced polymer materials systems. Conductive materials include metal coated carbon fibers and nonwovens, along with nickel nanostrands. The performance capabilities of the materials have now been extended and tested to include broadband ...
