The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of attaining this objective will be demonstrated by conducting a series of subscale experiments based upo ...

This proposal is directed at creating discontinuous unidirectional composite from continuous unidirectional prepreg. The process, Selectively-Discontinuous-Fiber (SDF), introduces micro-cuts in preimpregnated unidirectional materials at specified locations. This process will allow unidirectional composite prepreg to be used for the fabrication of complex-compound components that have be ...

The 3DIC concept is based on using multiple levels of thin film dielectric material, each having its own ground plane and microwave circuits, to stack up multiple circuit functions on top of each other. This approach reduces the IC footprint thereby reducing the usage of the semiconductor real estate, leading to substantial reduction in cost as well as improvement in performance. The phase 1 tec ...

This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative human-computer controversy over how to implement such capabilities, including how to ascertain the ...

Recent trends in the closure of military installations, requirements for the demilitarization and disposal of energetic materials and munitions, and environmental remediation obligations have produced a corresponding requirement for efficient processes which can detect the presence of energetic or explosive materials, extract them from the surrounding soil, air, or water, and modify or convert the ...

This Phase I SBIR will develop a general purpose probabilistic finite element analysis system, ProFEA, that allows designers to perform probabilistic finite element analysis in a graphical environment that is completely familiar and similar to modern deterministic FEA. We have developed an innovative architecture that takes advantage of emerging file exchange and database standards (I ...

Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...
