"Tim Foecke, a retired forensic metallurgist who has
done mechanical testing and failure analysis on metals
and carbon fiber, said the change in hull geometry
from a tight sphere to a lengthy tube may have contributed
to Titan's catastrophic failure. A larger hull needs to be
stronger and thicker to withstand the same pressure as a
smaller one. In two hulls of the same thickness, he said,
the larger one would "collapse or buckle" first."
