Roman helmets: Imperial Gallic/Italic and Ridge - comparisons and sources

[CaesarAugustus]

You are continuing not to reply on topic...

And then you start discussing motorcycle helmets...

Do you have an accurate replica of a ridge helmet? Have you stress-tested it and compared the results to similar tests on a Gallic/Italic type?

If not:

Can you demonstrate why a wealthy, organised and effective Roman state would start producing poor quality helmets to equip its army and continue doing so for 150 years, without anyone noticing or commenting?

If both answers are 'no', then I'm afraid there can be little substance to this debate!

Come on, read better

I have used different sources and the theory can be applied without any issue to military helmets. Discontinuous materials don't transmit forces, they need to be connected somehow and this connection is poorer than a contiguous piece of material. If you take that helmet and make it also monoblock, you'd still have a better helmet than one made by joining two plates. Continuity is a prerequisite for forces to transmit from one molecule onto another molecule at the molecular level. This is purely material science.

This is a problem that prevent the spread of the force on a greater area, so this increase the probability that the soldier is compromise. It is the beauty of mathematics, it is exact and not subject to opinions. Material science, and you cannot deny this, so I am afraid that you don't have any real substance, just useless diversions and theories denied that you don't want to abandon
