This is pretty far afield for this newsgroup. The Titanic was riveted iron. The iron was very brittle due to high sulfur content. Riveted iron is much weaker contruction than welded steel, particularly for a glancing type of collision. Many many seams would have been sprung and leaked badly without total failure. Similarly many of the iron sheets in the hull would have cracked and leaked without total failure. No doubt a lot of rivets heads were scraped off the outer hull as well. The Titanic is not likely to have suffered much metal fatigue by the intended midpoint of her maiden voyage. I do not see much similarity between the two beyond the fact that neither the Titanic nor the comets had adequate contruction to deal with the slings and arrows of their respective environments.
