For further research on the penetration resistance of the HPS (Honeycomb-like Protective Structure), more cases were simulated considering the key factors influencing the penetration including point of impact, angle of impact, and projectile caliber.
Partition-type bullets could be relied upon to retain at least 65 percent of their weight no matter what the angle of impact. They became widely popular among hunters of all types of game and spawned a family of derivative offshoots from a variety of other makers, such as Swift Bullets' tough-jacketed "A-Frame" series.
Bloodstain pattern analysis involves studying blood spatters on walls, floors and furniture, using the length and width of elliptical stains to estimate their angle of impact.
"Unfortunately the angle of impact with the barrier was such that the damage could not be repaired, and the rules don't let you use the spare chassis."
fig no.4.1 shows the mass loss at 90[degrees] angle of impact. But here it shows that the mass loss decreases as velocity increases at 75m/s velocity, loss of mass in ten minutes is just .001g.
Since the angle of impact changes, as a deer moves, this target permits an archer to practice shooting from three different angles.
This spherical shape of blood in flight is important for the calculation of the angle of impact of blood spatter when it hits a surface.
These types of fuze are particularly effective in mortar rounds due to the bomb's high angle of impact. Most fragmentation from the bursting round is released in sideways directions.
He checked her fractionally to assess the angle of impact, then gave her a kick in the belly and the equine assassin passed harmlessly just behind.
WrExpert is a complementary technology to EDR systems because EDER technology: 1) has sensitivities to non-frontal collisions that must be carefully evaluated; 2) cannot derive point and angle of impact; and 3) cannot independently assess accident implications to the other vehicles and their occupants.
Experts at the Poultry Research Unit at Glasgow University attempted to discover the top-ranking type of tool to use, the optimum angle of impact and best amount of force to use.
