Projectile momentum versus penetration


However, the results we found here would likely be altered if we used materials with different properties. Using both models, which would show the most difference between depth and capacity for penetration and percentage of increase or decrease of the respective value KE or MO. The strain rate of materials is key to understanding how fracture will propagate during impact events [ 34 ]. These results indicate that less energy is lost due to deformation when arrows are fired at higher speeds. These lower frame rate videos were not used for kinematic or puncture measurements. Eventually, the arrow comes to a complete stop, all forward movement is halted.

Point of impact: the effect of size and speed on puncture mechanics

The affected region is coloured in while the black oval represents the projected area that was measured for comparison with kinematic variables. These lower frame rate videos were not used for kinematic or puncture measurements. High-speed videos taken under cross-polarized light of arrows impacting ballistics gel illustrates how materials react to puncture events at high speeds. Bone 10 , — Also remember that two-dimensional motions can be broken up into 2 independent 1-dimensional motions, or components. Patek for help in experimental design, S. Stress waves are clearly visible 3.

High-speed videos taken under cross-polarized light of arrows impacting ballistics gel illustrates how materials react to puncture events at high speeds. The kinematic and puncture data taken from videos are available in the electronic supplementary material. The nature of multi-layered bio-composites leads to further questions about the scale of tool morphology and prey material. Data analysis Position data for the arrow in each frame of the videos was collected using the program ImageJ [ 31 ].

Projectile momentum versus penetration



Description: Introducing the lastest products from the worldwide leader in ammunition. Arrows of identical shape but varying in mass and speed were shot into cubes of ballistic gelatine. However, the mechanical goal of both behaviours is the same: Animals across four phyla and spanning a sevenfold range in size use high-speed projectiles to puncture during prey capture or defensive behaviours.
