Hello, I have a structural questions.

Today, helmets are mainly monoblock. In ancient times, there were some types that were made flanking different parts, kept togheter by using a ridge.
Here, you can see an example:


You can see the central ridge, and eventually the pivots that keep the structure united.

To me it is quite logical that a monoblock structure is more restitent compared to one in which the shots are absorbed by some pivot. And this is a good reason for which today the helmets are monoblock. But, do we have models and studies that describe this from a mathematical perspective?


Thank you,
