Titanic: Hull Materials & Construction - Get Answers Here!

SUMMARY

The hull of the Titanic was constructed using steel that contained a high sulfur content, which contributed to its brittleness and susceptibility to brittle fracture. The primary failure point during the sinking was identified as the rivets, which were made using a cold stamping method that created microscopic cracks, leading to their failure under stress. Investigations revealed that the hull damage was not a single gash but rather multiple small tears caused by rivets popping out and hull plates separating. Modern steel and riveting techniques would have significantly improved the hull's resilience compared to the materials used in the Titanic's construction.

PREREQUISITES
  • Understanding of metallurgical properties, specifically regarding sulfur content in steel.
  • Knowledge of historical shipbuilding techniques, particularly riveting methods.
  • Familiarity with structural failure modes, including brittle fracture.
  • Basic research skills, particularly in using targeted keywords for effective online searches.
NEXT STEPS
  • Research modern steel properties and their impact on structural integrity.
  • Learn about the cold stamping process and its effects on material durability.
  • Investigate historical shipbuilding practices and how they have evolved over time.
  • Explore case studies on structural failures in maritime engineering.
USEFUL FOR

Historians, metallurgists, shipbuilders, and anyone interested in maritime engineering and the Titanic's construction and failure analysis.

i'd like to know about the materials that were used to build the hull of the titanic?...i'v googled it,,, but i suck at finding info so bad, can anyone help?

great, thanks a lot friend
 
You're welcome. Googling is a matter of deciding what the important key words are. In this case it was easy. "Titanic" alone would be too broad, if that's what you were trying. "Titanic hull" might have worked, but "Titanic hull material" is best since that is specifically what you want to know.
 
hmmm...the actual question says "find out about the materials used to build the hull of the Titanic.Create list with a brief description of each material"

its so hard to find good info about this stuff, maybe someone can help
 
I recall a prof. saying the steel had a high sulfur (sulphur?) content, raising its embrittlement transition temperature. I think the mode of failure was found to be brittle fracture.
 
They now believe that the cause of the hull breach was due to the rivets popping out, thus allowing the steel plates to separate. This was a combination of the riveting method used and the brittleness of the steel due to high sulphur content.

-------
Considerable hullabaloo attended the attempt in the summer of 1996 to raise a piece of the hull from the debris field, but far more interesting was the ultrasound investigation of the area of the bow damaged by the iceberg. These images revealed six small tears or openings affecting the first six compartments. Just as we had surmised in 1986, the great gash was a myth and the actual openings into the ship seem to have been the result of rivets popping and hull plates separating.

•The steel used to construct Titanic was rather brittle. Today's steel would have bent more easily, thus resisting complete failure better than Titanic did. Even for its day, Titanic's hull contained more sulphur than usual, which contributed to its brittleness.

•The point of failure on the hull was at the steel rivets, which, when a 90 degree sheer was applied to them, caused them to pop out like popcorn. The method of creating rivet holes at that time was known as "cold stamping," which involves a cutting machine ramming the steel when it is cold. This process creates microscopic cracks at the hole, which made it that much easier for the rivets to pop loose. Modern rivet holes are made while the steel is still hot, when riveting is used at all.

Yes- recall some mention of rivets too.

I'm amazed, there is a current forum on the Titanic where you can ask questions about the Titanic and get a real time response.

Go to the message board and ask your questions.
