A drift-diffusion-like formulation for including ballistic and quasi-ballistic transport in the simulation of double-gate MOSFETs has been implemented in a technology computer-aided design (TCAD) simulator. This model is based on a description of the quasi-ballistic mobility through a dynamical description of the mean free path.

Ballistic impact performance of metallic targets
Materials & Design, 2012Abstract Performance of metallic targets under ballistic impact loading is presented. The entire ballistic impact event considering target performance can be divided into dynamic plastic penetration, spherical bulge formation, bulge advancement, plug formation and exit and projectile exit. Velocity, displacement, force, deceleration of the projectile

Ballistic performance of multi-metal systems
International Journal of Protective Structures, 2020Ballistic resistance enhancement of armours and structures has been a prominent area of research over the years. Monolithic metallic plates have been the preferred choice for armours against high-velocity projectiles. High-strength steel is a popular choice for such systems.

The influence of projectile hardness on ballistic performance
International Journal of Impact Engineering, 1999The ballistic performance of 17 penetrator materials, representing 5 distinct steel alloys treated to various hardnesses along with one tungsten alloy, has been investigated. Residual lengths and velocities, as well as the ballistic limit velocities, were determined experimentally for each of the alloy types for length-to-diameter (L/D) ratio 10 ...

Performance analysis and enhancement of the ballistic range
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2007The ballistic range has long been employed in a variety of engineering fields such as high-velocity impact engineering, projectile aerodynamics, and aeroballistics, since it can create an extremely high-pressure state in a very short time. Of many different types of ballistic ranges developed to date, a two-stage light-gas gun is being employed most ...

Ballistic performance of ceramic/composite structures
Ceramics International, 2019Abstract The aim of this study is to investigate the ballistic behavior of ceramic/composite structures with different thicknesses and different reinforcements, numerically. The guns were shot at four different velocities on composite models using armor-piercing 7.62 M61 AP projectiles.

Ballistic Performance Prediction for SC Jets.
30th International Symposium on Ballistics, 2017The performance of a shaped charge warhead is usually predicted based on an experimentally determined standoff curve valid for a specific target material. However, with the increased variety of target compositions the traditional “shoot and score” approach is not feasible anymore – neither financially nor with respect to time. In this paper, a combined

Ballistic performance of composite metal foams
Composite Structures, 2015Abstract The application of advance materials to manufacture hard armor systems has led to high performance ballistic protection. Due to its light-weight and high impact energy absorption capabilities, composite metal foams have shown good potential for applications as ballistic armor.

Effect of Microstructure on the Ballistic Performance of Alumina
1971Results of a study of various dense Al2O3 bodies using a 22-caliber fragment simulator are presented showing that there is no significant correlation of ballistic performance with static tensile strength, surface finishes or single crystal orientations.
