Hello all,
I have copied the replies I had from Biomch-l users on this query. As always the information was extremely useful. I would like to sincerely thank everyone who replied to me.

Hello all,
I have recently read the paper
Development of biomechanical response corridors of the thorax to blunt ballistic impacts, Bir C, Viano D, King A, JOURNAL OF BIOMECHANICS
37 (1): 73-79 JAN 2004.
and
Analysis of injury criteria to assess chest and abdominal injury risks in blunt and ballistic impacts
Sturdivan LM, Viano DC, Champion HR
JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE
56 (3): 651-663 MAR 2004
These papers both fully explain the best predictors for high-speed ballistic impacts for the chest.
Does anyone know of any similar papers which deal with the high-speed, low-mass projectile impacts to the head. I assume that the HIC is not used to assess tolerance to these impacts as the drop tests from which the HIC was derived were of low impact velocity.
If anyone has any contacts or references that cover the tolerance of the head to high-speed blunt impacts I would really appreciate it if you could email them to me.
Many thanks

Hello,
A NATO working group on Behind Armor Blunt Trauma (BABT) has done some
related work (head protected by a helmet) but I do not have the references.
Cameron R. Bass has done some work on the subjet at the University of
Virginia, you might try to contact him.
best,
Quentin

Cory,
I am not sure of the specific type of head injury that you are referencing.
I would expect that if you are studying generalized concussion then you should
study Ommaya and other researchers work related to angular acceleration.
(Let me know if you need any references.) Below is a reference that shows what
helmeted subjects that sustain blunt projectile objects are able to sustain
without LOC.
"Voluntary Tolerance of the Human to Impact Accelerations of the Head."
Charles F. Lombard, Et al. Aviation Medicine April 1951 pp 109-116.
In additition, here is a ref related to biomechanical studies on boxers.
"Some New Data Related to Human Tolerance Obtained From Volunteer Boxers."
Y. Pincemaille, et al. SAE 892435
This is another paper that measured the g's that the head sustained when
heading a soccer ball and when involved in other sporting events.
"Comparison of Impact Data in Hockey, Football, and Soccer" R.S. Naunheim, J
Standeven, C. Richter, L.M. Lewis, Journal of Trauma 48(5):938-941.
I hope this helps you. Good luck in all of your efforts. Would you please
send me a copy of whatever you learn?
Best wishes,
Matt

Dr Cory,
In response to your recent query on BIOMCH_L, Dr. Philippe Young and myself have published papers on blunt, low-mass
projectile impacts to the head using analytical, experimental and finite element models. The experimental work has concentrated on relatively low mass impacts (1-3m/s) but you may well find some of the following useful:
Young, P. G. and Morfey, C. L., (1998) Intracranial pressure transients caused by head impacts, Proceedings of the 1998 International IRCOBI Conference on the Biomechanics of Impact, Goteborg, Sweden,
Young, P. G., (2002) Response of the human head to impact: understanding brain injury mechanisms, Proceedings of an Advanced Workshop on Mathematical and Computational Modelling of Biological Systems, Lisbon, Portugal,
Young, P. G. (2002), A parametric study on the axisymmetric modes of vibration of multi-layered spherical shells with liquid cores of relevance to head impact modelling, J. Sound & Vibration, 256, 665-680.

I hope this helps

Dr. Cory:
My name is Benoit Anctil and I work for Biokinetics and Associates Ltd. We have an active program in developing a test method to assess the performance of ballistic helmets under non-penetrating impact (i.e. when the bullet is defeated but the deformation is such that it can cause serious injuries). It is led by Defence Research and Development Canada Valcartier and involves collaboration with NIST/OLES through the US/Canada bi-lateral agreement on counter terrorism research and development (TSWG). Our work is based on studies conducted by the NATO specialists team on behind armour blunt trauma. It involved mainly the Defence Research and Development Canada Valcartier, the US Army Natick Soldier Center (research conducted at the University of Virginia for), and the Délégation Générale pour l'Armement in France.
I've indicated below some references summarizing these researches. You can also contact Dr. Bir (bir@rrb.eng.wayne.edu) at Wayne State University, she did recently a study on ballistic impact to the face.
Hope that helps,
