Ballistic penetration data

The present work sets the background for further development of theoretical penetration models incorporating material properties and parameters of the projectile—target pair. Abstract Determination of ballistic performance of an armor solution is a complicated task and evolved significantly with the application of finite element methods FEM in this research field. Why are they so tight? Will you do ballistics test of the Lehigh Defense Extreme Penetrator chambered in 45 acp. Unlike penetration, there is no widely accepted minimum standard for expansion. The photography and videography is par excellence seriously, I want a behind the scenes with the photographer on this gig. The chart shows the penetration depths in order of least to greatest, not in the order fired.

Ballistic-penetration resistance and its measurement

Similar, but not identical, trends, are evident for the six tile configurations, whereby projectile defeat occurs only when polymer is omitted, with nonzero residual velocities reported whenever polymer layers are included. I like the load and the local PD use it and have tested it pretty thoroughly. I have no reason to believe that this contributes to any wounding effect, but it does look cool. If anything, I would think the potential for the sharp petals to cut through tissue would actually make them slightly more effective. When plastic deformation occurs, the yield condition is enforced numerically via a radial return algorithm.

Figure shows the BFD measurements by shot locations. Actually, the Hornady Critical Defense in did well in these tests compared to the rest. With similar arguments, V max. This failure to expand gives the bullet a lower probability of striking a vital area, and also leads to the potential for over-penetration. The first condition depends on the person operating the gun. In certain penetration events it is proposed that the primary mode of deformation of the target can be approximated by known analytical expressions.

I think perhaps Golden Sabers expand a little more reliably with more velocity … on this test at least the s seem to consistently end up in the sweet spot. To show the effect of nose shape, we compared penetration data for the spherical-nose projectiles with previously published data for ogive-nose projectiles. Bullets that expand or tumble will leave a bigger wound cavity than bullets that fail to expand. Of the 12 shells, 3 are conditioned in each of four different environments. I did not see any notes about calibrating the gel or temperature of the gel blocks. The upper 90 percent confidence limit on the probability of exceeding the limit, based on this outcome, is about 9 percent, so the 10 percent standard is met in this regard.
