BRIEF HISTORY OF TITANIC
German-Mongolian Institute for Resources and Technology − www.gmit.edu.mn
31 March
1909
• Construction of titanic begins
31 May
1911
• Firstly launched
10 April
1912
• left Southampton
• called at Cherbourg (France) and Queenstown (Ireland)
• Headed to New York
14 April,
11.40pm
• hit an iceberg
15 April,
2.20am
• broke apart and sank with over 1500 people
September
1, 1985
• The wreck of Titanic was first discovered at depth of 3784m

• FULL SPEED
• (42KM/H) DURING NIGHT
TIME
• ICEBERG WAS SPOTTED TOO
LATE
(37 SECONDS BEFORE HIT)
• THE LACK OF LIFEBOATS
• HULL STEEL
• DESIGN

TITANIC STEEL VS MODERN STEEL
German-Mongolian Institute for Resources and Technology − www.gmit.edu.mn
TITANIC
STEEL
SAE 1020
GRAIN SIZE 50µm 25µm
Yield
Strength 193.1 MPa 206.9 MPa
Tensile
Strength 417.1 MPa 379.2 MPa
MN:S RATIO LOWER HIGHER
DUCTILE-TO-
BRITTLE
TEMPERATURE
GREATER
(32°C for
longitudinal
56°C for
transverse)
LESS
Sea-water temperature (-2°C) below DUCTILE-TO-
BRITTLE TEMPERATURE (32°C and 56°C) led to
brittle failure

DESIGN FLAWS OF TITANIC
German-Mongolian Institute for Resources and Technology − www.gmit.edu.mn
• The lower section of the Titanic was divided into
sixteen compartments that could easily be sealed off
• If there had been no compartments at all, the incoming
water would have spread out
(Titanic would have remained horizontal for another 6
hours)
TITANIC STEEL
WHICH SHOWS
BRITTLE BEHAVIOR
UNDER 32°C

7. Implemented by:
CONCLUSION
• THE MAIN ENGINEERING
MISTAKES OF TITANIC WERE
1. HULL STEEL
(SHOWS BRITTLE BEHAVIOR
UNDER 32°C)
2. BAD DESIGN IN LOWER
SECTION
German-Mongolian Institute for Resources and Technology − www.gmit.edu.mn
• SOLUTION WOULD BE
1. PROPER STEEL (WHICH HAS
LOWER DUCTILE-TO-BRITTLE
TEMPERATURE)
2. NO COMPARTMENTS
