Battle damaged combat police helmet

[Fred S]

I hope you guys are taking notes and there will be a test at the end of this thread. The professer has of course greatly simplified the physics involved here to make it easier for the layman to grasp the general theorem

...but I think we can all at least understand the cleavage bit...

If you ask me in a week I'll get a D....

I agree with what the professor wrote, but would like to add a couple of comments:
-The way a helmet will react to stress is very variable depending on the model and nationality of the helmet: US helmets, French helmets, and German helmets dont get damaged in the same way, and mdl 35 helmets dont get damaged like mdl 42 helmets do. I wonder what model of helmet all this testing was done on...
-Although the I agree that the cracks on helmets may be caused by explosions, I am sure that they can be caused by many other phenomenon as well.

For me, these helmets with cracks probably were defective from the start, and were waiting for a "trigger" to crack. The helmet posted by Wolhans actualy does have a small dent if you look carefully, that dent was the trigger.
Considering that the cracked helmets I usualy see have no other apparent damage, I think that the trigger that caused the helmet to crack is most of the time not related to an explosion.

I actualy did hit a german helmet (crappy shell) with a pick axe once. I made one hole and several dents. Over the next weeks, several cracks appeared, related to the dents I had made.

I don't consider a German Helmet to be "CRAPPY" in any condition, unless of course someone decides to hit it with a pick axe.

Seems to me like that is an odd way to pass the time.

I would agree with you now, but that was several years ago.
It was a helmet given to me in a deal where older collectors ripped me off, and I somehow transmitted my rage against the collectors onto the helmet.

PS: I have a battle damaged relic shell for sale right now. It has one hole and several dents and cracks: surely a close range artillery hit!! PM me if interested.

Look at the cracked dog tag on the first photo here: http://dev.wehrmacht-awards.com/foru...262256&page=19

Why is it cracked and not the others? Who knowns, but I doubt it has anything to do with a concussion...
