What happened to Titanic Ship actually..?

You see... metals undergo yielding till some point. But brittle ones break when impact is there just like glass. Titanic was travelling in very cold waters which made the metal (ship made up of) kinda brittle in nature. When it hit the ice berg, it got shattered like glass and water kept coming in. Eventually it sank. Understanding these phenomenon helped people to manufacture materials which can overcome this kind of problem (brittleness).
