Introduction:
The basic components that are required to build a ship is same for all kinds of ships. The materials
that are required to build a ship are steels, aluminum, plastic, iron core and may more based on the
type and size of the ship. In this particular task the mechanical materials needed to build one Cruise
ship is provided along with an approximate design of the ship. All the mechanical stress, strain,
breaking stress of the materials are calculated using scientific methods that will allow long term
stability of the ship. The final chosen materials for building the ship is decided based on the
calculations and the results obtained in previous articles where similar kinds of ships were
manufactured.

Plan for Ship design:
The ability of metal and non-metal materials that are used in building ships. There are numerous materials
that are used in building ship, including ferrous metals as well as non-ferrous metals, GRP (Grass Reinforced
Plastics/fiber glass), wood and plastics. Steel is the material that is widely used in projects of shipbuilding.
Steel has very good metallurgical properties which helps it to overcome fatigue and brittle fracture. Steel that
consists very low carbon has tensile strength of around 400 to 490 MN/m2 and yields strength of around 235
MN/m2 (Cullen 2018). It elongates around 15 to 20% (Desai, Prajapati and Patel 2016). Steel has the ability
to be treated with heat. Alloy elements can be used to change various characteristics of steel. Carbon can be
used in order to increase hardness as well as strength, it also reduced ductility. Manganese increases the
tensile strength, notch toughness and ductility. Silicon is used in order to increase tensile strength and
hardness, it makes welding very easy. Sulphur makes welding easy and reduces the complexity in weald
ability. Phosphorous improves the level of ductility and toughness.
