The relationship between strength, power and ballistic performance
Journal of Electromyography and Kinesiology, 2009The purpose of this investigation was to answer the question, "Does Stronger Mean Faster?". After a screening for elbow strength and speed, four groups of 8 subjects were selected for further investigation that fell into the extreme quartiles of the strength and speed continuums.

Relationship between isokinetic performance and ballistic movement
European Journal of Applied Physiology and Occupational Physiology, 1983The present experiments were carried out to assess the relationship between the mechanical behaviour of the leg extensor muscles in 12 male athletes during activities of a ballistic type and torque production, during: (1) torque production during isokinetic contraction: (2) ballistic type activities (vertical jumps from statis position = SJ, with ...

A Study on the Ballistic Performance of Composites
Macromolecular Symposia, 2006AbstractThe mechanical behaviour and ballistic performance of carbon, glass (E and S type), aramid and polyethylene fabric reinforced composites with different epoxy resins were studied. The specimens – produced by hand lay‐up method – were characterized by low velocity (Charpy and drop‐weight tests) and high velocity (two different calibre ballistic ...

IEEE Transactions on Electron Devices, 2008
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 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 ...

Engineering and analysis of gripping fabrics for improved ballistic performance
Journal of Composite Materials, 2014 Previous studies show that fabric construction is one of the key factors affecting the performance of ballistic fabrics. In order to investigate the effect of yarn gripping in fabrics, plain woven narrow fabrics with different widths have been designed ...

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 ADHESIVELY BONDED JOINTS
Proceedings of the 32nd International Symposium on Ballistics, 2022In this study, ballistic performance of adhesively-bonded Single Lap Joints is investigated experimentally and numerically. Using a specially-designed experimental set-up, a projectile with mass of 1.25 gr and density of 11.3 gr/cm3 was fired to the joints at a velocity of 288 m/s.

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.
