thats only .1 less than the air pressure at sea level. 4/25/2009 1:08:53 PM |

Thanks for this unusal question, to which there are several variables. The skull in an individual of course is not uniform in shape or thickness and of course skulls vary in these aspects in different people, and so the amount of force to fracture or "crush" a human skull varies on the particular skull and at what point the force is applied. It also depends if the skull is with or without skin hair etc....
However the links below help to answer your question.
"It only takes 33 ft pounds of energy to fracture a skull, or approximately 398 inch pounds of energy" http://www.eijkhout.net/rad/dance_other/health4.html
"It takes about 250 to 350 ft/pounds to fracture the skull, which is close to the rib fracture energy above." http://www.kenrahn.com/JFK/Issues_and_evidence/Frontal_shot(s)/Tobias_frontal_shots/Head_snap.html
"for a contact area ofapproximately 1 square inch (6.5 cm2) the forcerequired to produce a clinically significant skullfracture in the frontal area of the cadaver skull was twice that required in the temporoparietal area." **PDF DOCUMENT** http://www.edc.gsph.pitt.edu/neurotrauma/thebook/Chap02.pdf
"a force of 73 Newtons is enough to cause a simple fracture, this force is the equivalent of walking into something solid. An unrestrained adult fall from standing has been shown to produce a minimal force of 873 N which is more than enough to produce a skull fracture." http://www.portfolio.mvm.ed.ac.uk/studentwebs/session2/group62/head.htm
NOTE* to convert Newtons to pounds multiply by 0.2248 in the above case 73 newtons=16.4104 and 873N=196.2504 lbs
So, the force required to crush a human skull is (aproximately) between 16 and 196 pounds.
I hope this answers your question sufficiently. If you need any clarification please do not hesitate to ask.

I had to look this up once for my forensic engineering job
cant remember the answer, but that was a wild job
I do remember it depends on how big the object is that you are hitting it with and where on the skull you are cracking. I think its easier to crack the sides than the front

it's like 2000 to break a femur, so probably in the 1000-1500 range?
I guess it also depends on which part of the skull we're talking about

^^ no shit.
According to this: http://www.fightingarts.com/ubbthreads/showflat.php/Cat/0/Number/15756092/an/0/page/2
1400psi
I am a good guesser. 4/25/2009 10:27:12 PM |
ThePeter TWW CHAMPION 37709 Posts user info edit post |
my sources said 15 psi
so
i dunno, it depends 4/25/2009 10:51:14 PM |
