Share1 Shares I wanted to challenge myself and try to come up with a list that did not just look back on history but also, tried to predict it. So I came up with a list of predicted dates by which the last known veterans of 20th Century wars will die. Unfortunately there are many 20th Century wars and conflicts to choose from. I am fascinated with last survivors of any historic event.
The stern raises up out of the water; the bow, filling with water, grows heavier. The damage caused by the collision allowed water to flood six of the sixteen major watertight compartments.
By midnight, water in the damaged compartments began to spill over into others because the compartments were watertight only horizontally and the walls extended only a few feet above waterline.
Flooding progressed until, at about 2: At an angle of 45 degrees or more, the stresses in the midsection exceeded the ultimate stresses of the steel and the steel failed [Garzke and others, ].
Stresses at failure were estimated at nearly 15 tons per square inch [Gannon, ]. What survivors of the disaster then described was a loud noise that sounded like breaking china or falling equipment [Hill, ].
The bow, dangling beneath, continued to fill with water. Free from the weight of the bow, the stern rose again sharply to an almost vertical position. Slowly filling with water, the stern began to sink into the water. Meanwhile, the bow had been coasting down at about 13 miles per hour mph.
Falling nearly vertical at about 4 mph, the stern crashed into the ocean floor 27 minutes later. The two pieces of the Titanic lie 2, feet apart, pointing in opposite directions beneath 12, feet of water. The bow section remains mostly intact, although the damaged portion of the hull is covered with a foot high wall of silt and mud that plowed up when the Titanic hit bottom, so the point of fracture can not be seen.
The stern section is a tangled wreck, as implosions occurred during the descent due to air trapped within the structure succumbing to the increased water pressure at greater depths. Between the two sections is a wide field of debris [Hill, ].
For 73 years, the Titanic remained undisturbed on the ocean floor. On September 1,oceanographer Bob Ballard and his crew discovered the wreck of the Titanic about miles southeast of Newfoundland, Canada [Gannon, ]. Since then, four more expeditions have visited the Titanic.
Inthe first purely scientific team visited the site. The dive was called the Imax dive because the purpose was to create a film for Imax theaters.
The Soviet submersibles used in the dive were capable of staying submerged for twenty hours and were equipped withlumen lamps. With this equipment, scientists were able to take pictures of the Titanic wreck and eventually uncover new evidence into the cause of the Titanic disaster.
The Frisbee sized piece of steel was an inch thick with three rivet holes, each 1. Since the retrieval of this piece of steel, extensive research has been done to uncover additional clues to the cause of the rapid sinking of the Titanic. The following is a discussion of the material failures and design flaws that contributed to the disaster.
Material Failures 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:Aug 30, · A look into the events that occurred during the sinking of the Titanic.

A metallurgical analysis of steel taken from the hull of the Titanic's wreckage reveals that it had a high ductile-brittle transition temperature, making it unsuitable for service at low temperatures; at the time of the collision, the temperature of the sea water was -2°C.
The analysis also shows, however, that the steel used was probably the best plain carbon ship plate available at the time. The RMS Titanic, a British Olympic class ocean liner, became famous as the largest ocean liner built in her day and infamous for sinking on her maiden voyage, in This event ranks as one of the worst peacetime maritime disasters in history.
On the night of April 14, at p.m., the ship struck an iceberg and sank in just under three hours . Alternate History. Due to time constraints I can no longer update the contents page.
