Were the rivets weak?

There is a new theory going around that the rivets on Titanic were weak, and that they popped on impact because that they were weak. However, Parks Stephenson, a Titanic expert, conducted a rivet test using near exact replicas of Titanic's rivets. He finds that the rivets were not weak. But, if the rivets weren't weak, how did the iceberg flood 6 compartments? Well, on impact, rivets did pop. Not because they were weak, it was because the force was simply overwhelming.
