Sea water originally entered into the ship through a small hole in the hull that was only about three by four feet across
"Though the damage in the hull was 220 to 245 feet long, the most recent evidence shows that there was only a 12 square foot opening,the size of a refrigerator,in the hull allowing water inside the ship"... Hmmmmm...I knew it! www.eszlinger.com... < look under collision/damage... A 12 foot hole equals torpedo damage imo,not from scraping against a gigantic ice berg...

The Myth Of The 300ft Gash > www.rmstitanic.net...
It wasn't until 1996 that ultrasonic probes conducted by Paul Mathias were able to conclusively establish that there was no gash: the damage done was indeed a series of bent plates, split seams and small holes--the total area open to the sea being just a little over 12 square feet.
it doesnt say that 12ft square hole represented the total area damaged > www.eszlinger.com...

I wonder how frequently icebergs large enough to sink a passenger liner are seen within the same area as where the titanic supposedly encountered one?
Just how massive would an iceberg have had to be,in order for it to be able to tear apart steel?
Would'nt the floating and moving iceberg needed to have been heavier than the ship itself,much more than the 52,310 ton titanic?
Go outside and try smashing a 3/4 inch thick piece of steel against a block of ice,or drop that piece of steel onto a block of ice from high above,or even shoot that piece of steel out of a cannon against a block of ice and watch what happens,steel wins,ice loses,everytime...edit on 29-6-2012 by blocula because: (no reason given)
Makes no sense to me at all that the designers and owners of the titanic would allow the use of brittle steel for the ships hull and wherever else,to save money? but then build the titanics interior so lavishly and expensively...

Um. they sure would use cheap steel to build the titanic. wanna know why? Cause it's cheaper and rich folk don't like spending money that doesn't help their bottom line. nobody's going to know we laid the keel using inferior metal. Hull plates neither! besides they will be in too much awe of our luxury linens, dishes, furniture and woodwork through out the ship to notice.
So yeah they would use cheap metal for parts of the ship not seen or considered by the paying passengers and public.
The steel used to build the Titanic was not as "impact-resistant" as modern steel, according to Dr. H.P. Leighly, a professor emeritus of metallurgical engineering at UMR. But it was the best steel available at the time, says Leighly, who studied some 200 pounds of steel from the wreckage.
Leighly's paper, co-authored by UMR metallurgical engineering student Katie Felkins, will appear in the January 1998 issue of Journal of Metals, the publication of the American Institute of Mining, Metallurgical and Petroleum Engineers.
Inferior steel wasn't the only reason the luxury ocean liner Titanic sank in the early morning hours of April 15, 1912. Other factors -- such as flaws in the ship's design, the crew's negligence and the lack of lifeboats -- also contributed to the disaster, Leighly says.
"The naval architects can point their fingers and say, 'It was bad steel'" that caused the Titanic to sink, Leighly says. "It's easy to point a finger and say, 'Bad steel.' But it's uncomfortable to point at yourself and say, 'Bad design.'"
When the Titanic collided with the iceberg, the hull steel and the wrought iron rivets failed because of brittle fracture. A type of catastrophic failure in structural materials, brittle fracture occurs without prior plastic deformation and at extremely high speeds. The causes of brittle fracture include low temperature, high impact loading, and high sulphur content. On the night of the Titanic disaster, each of these three factors was present: The water temperature was below freezing, the Titanic was travelling at a high speed on impact with the iceberg, and the hull steel contained high levels of sulphur.
The Hull Steel. The first hint that brittle fracture of the hull steel contributed to the Titanic disaster came following the recovery of a piece of the hull steel from the Titanic wreck. After cleaning the piece of steel, the scientists noted the condition of the edges. Jagged and sharp, the edges of the piece of steel appeared almost shattered, like broken china. Also, the metal showed no evidence bending or deformation. Typical high-quality ship steel is more ductile and deforms rather than breaks [Gannon, 1995].
Similar behavior was found in the damaged hull steel of the Titanic's sister ship, Olympic, after a collision while leaving harbor on September 20, 1911. A 36-foot high opening was torn into the starboard side of the Olympic's hull when a British cruiser broadsided her. Failure of the riveted joints and ripping of the hull plates were apparent in the area of impact. However, the plate tears exhibited little plastic deformation and the edges were unusually sharp, having the appearance of brittle fractures [Garzke and others, 1994].
Further evidence of the brittle fracture of the hull steel was found when a cigarette-sized coupon of the steel taken from the Titanic wreck was subjected to a Charpy test. Used to measure the brittleness of a material, the Charpy test is run by holding the coupon against a steel backing and striking the coupon with a 67 pound pendulum on a 2.5-foot-long arm. The pendulum's point of contact is instrumented, with a readout of forces electronically recorded in millisecond detail. A piece of modern high-quality steel was tested along with the coupon from the hull steel. Both coupons were placed in a bath of alcohol at -1°C to simulate the conditions on the night of the Titanic disaster. When the coupon of the modern steel was tested, the pendulum swung down and halted with a thud; the test piece had bent into a "V." However, when the coupon of the Titanic steel was tested, the pendulum struck the coupon with a sharp "ping," barely slowed, and continued up on its swing; the sample, broken into two pieces, sailed across the room [Gannon, 1995]. Pictures of the two coupons following the Charpy test are shown in Figure 1. What the test showed, and the readout confirmed, is the brittleness of the Titanic's hull steel. When the Titanic struck the iceberg, the hull plates did not deform. They fractured.
