What force (or velocity) is the minimum required to impale/puncture human flesh?

Question

talking about projectiles...

Thanks!

i'm referring to bullets, shotgun shot, and metal BBs

Answer 1

In terms of a super sharp needle into an eyeball, almost immeasurably small.

In terms of a blunt object into a toe nail, then a significant amount of force is required.

A domestic dogs which has relatively blunt teeth would have no trouble biting a human toe nail with only 320 pounds of force in the bite.

Answer 2

It depends mostly on the cross-section area of the projectile. A single gamma particle requires an infinitesimal amount of force. Velocity can be extremely small. Move a hypodermic needle slowly enough and you can take a year to penetrate. A minimum velocity would be enough to move from outside the flesh to inside the flesh in less time than it takes the flesh to decompose. A minimum force would be that required to move a single atom across the boundary, displacing atoms and molecules in the flesh just enough to make room for that one atom.

Answer 3

That's a hard one to answer. Mostly bcuz it all depends on what ur using to punture the skin...differnt things take more or less force(velocity)...a sharper object of course would take less than a more blunted object...or a pointed object and so on...so define ur question for me and maybe i can be more detailed :)

Answer 4

I really don't see any way to determine this just based on theory. I guess you would have to do an experiment.
