In this paper we present a compact model of DoubleGate MOSFET architecture including ballistic and quasiballistic transport down to 20 nm channel length. In addition, this original model takes into account short channel effects (SCE/DIBL) by a simple analytical approach. The quasi-ballistic transport description is based on Lundstrom’s backscattering coefficient given by the socalled flux metho...

We determine the impact force generated by the projectile penetrating the body of the harmonic oscillator.We discuss the ballistic effect in connection with the Compton effect.

Ballistic impact on composite panels is studied in this work both experimentally and computationally. The purpose was to develop computational methods to analyze a high speed jet engine fragment impacting on composite targets. 12 inch by 12 inch laminated panels with 8, 16, and 32 plies and the standard +-45, 0 /90 degree stacking sequences were considered. With the nominal ply thickness of 0.0...

BACKGROUND Currently, there is a greater use of nonlethal force in law enforcement and military operations. Because facial injuries have been observed, there is a need to understand the human response to ballistic impacts involving various regions of the face. This study aimed to establish blunt ballistic response corridors for high-speed, low-mass facial impacts to the forehead, zygoma, and ma...

The current body armor systems manufactured using ballistic fibers are not performing as theoretical results predict and are causing injuries. The actual maximum projectile penetration speed that the body armor can endure is significantly lower than the theoretical maximum speed, thus causing a costly build-test relationship that is not aided with modeling design efforts. The main aim of this r...

The purpose of this research is to simulate and test nanomaterial reinforced composites for potential applications in Army vehicles, especially for improved ballistic and blast protection. The resultant simulation and design system can address major concerns in functional requirements of nanomaterials in Army’s ground vehicles such as strength, durability, ballistic and blast impact resistance....
