The task of computationally simulating the dispersion and/or neutralization of toxic chemical/biological (CB) agents, released from weapons of mass destruction (WMD), puts a very high demand on the capability of current generation computational dynamics(CFD) codes. Current advanced computational tools for WMD threat simulation fail to address all the necessary physics, do not incorporate emerging ...

Upon successful completion of the proposed program, an accelerant payload concept shall be developed and evaluated. The use of an accelerant payload allows the munitions system designer the capability to exploit a thermal target defeat mechanism, inaddition to coupling to traditional high explosive/fragmentation defeat mechanisms, to increase the overall target lethality. The use of a thermal ac ...

DTRA and other DoD agencies are currently seeking earth penetrators with higher efficiency for reaching deeply buried targets. Current penetrator materials and designs suffer from high levels of frictional drag, unbalanced resistance due to lateral forces and localized melting of the warhead leading to shape change and further instability. General Sciences, Inc. (GSI) has developed a method for en ...

This proposal describes the application of a mature nanotechnology-based crack arrest / structural repair technology as a novel crack arrestor tool for high-strength pipelines. The crack arrestor would comprise a thin layer or sleeve of electrodeposited nanocrystalline material applied to the outside of the pipe either in the coating mill during fabrication or in-field during or following constru ...

This proposal describes the application of a mature nanotechnology-based crack arrest/structural repair technology as a novel in-field pipeline repair tool. The repair would be comprised of a thin layer or sleeve of electrodeposited nancrystalline material applied to the damaged region of the pipe in order to utilize the "crack filling" characteristic of the process. The concept proposed has alr ...

Laser Technology Inc. (LTI) proposes a Phase II SBIR research project to further develop a Compact Shearography System, Analysis Method and Software for micro-crack detection in concrete. There is an urgent need to detect and characterize fine cracks in concrete that form because of various damage mechanisms including alkali-silicate reaction, delayed ettringite formation or frost damage. Fine s ...

Simple, yet accurate engineering analytical tools will be developed for the evaluation of strength, durability and damage tolerance of composite bonded joints used in General Aviation (GA) structures with due consideration to adherend and adhesive thickness variations used (or present) in such joints. These tools and other available ones will be exercised for typical joint GA joint configurations ...

In the Open-source microscopic traffic simulation models project, a component based software framework is proposed to re-engineer CORISM data struture and CORISM interface. Under the architecture combing the innovative framework and the legacy CORISM, prototype of the open source traffic flow simulation models will be developed and demonstrated in the Phase I. In addition, areas identified by th ...
