My friend's characters are debating whether or not a swelling brain could cause a human skull to crack, and so my friend would like to know how many psi would be required to crack the skull from the inside.
She has searched "skull cracking from inside psi," "internal skull fracture," "internal skull strength," and "psi to break skull internally," but without any luck, so I offered to post her question here.
Any help is greatly appreciated by both of us. Thank you.
Edit: Thanks to those who have suggested herniation; however, this particular discussion is about the theoretical rather than the practical. So, assuming there were something (not necessarily the brain) inside the cranium exerting pressure, how many psi would it take before that something fractured the skull?
