There are 2 types of strengths that materials can be tested on: Comprehensive strength and Ultimate Tensile strength. Ultimate Tensile strength is measured by how much stress can a material withstand, while being stretched or pulled apart before breaking, while comprehensive strength is how much van the material resists while being pushed in (together). There is also a Yield Strength- the point at which the material starts to slowly break and cannot come back to it’s shape. Before the yield point of a material, it can come back to it’s shape. The following Ultimate Tensile strengths for 3 materials are: Copper- 220MPa , Aluminium- 40-50MPa , Iron- 3MPa. The following Yield strengths for 3 materials are: Copper- 70MPa , Aluminium- 15-20MPa , Iron- -. It can be said that copper is the strongest metal on it’s own, while aluminium is next and iron is the least. However, people can use iron as an alloy to create steel, which can be stronger up to 10x
Most of the metals in Periodic Table have high malleability. This also includes iron, aluminium and…

will include tensile strength,
tension, elasticity, and temperature. Information on these topics will also include how
their properties can differ, as well how they are affected under various circumstances.
The strength of materials and how different properties affect it can change the
circumstances they are put under.
Tensile strength is the resistance of a material put under stress. It is different than
compression or shear strength because of the direction of the force that the material…
Kevlar is a weaved fibre known as poly-paraphenylene terephthalamide. Kevlar is part of the aramid family. (Kevlar-The Super Tough Fiber)Aramid chemical name is aromatic polyamide. Aramids was the first organic fibre to reinforce advanced composites. The reason being it strength, and tensile modulus was high enough to be used in advance composites. The fibre mechanical properties of an aramid are higher then most materials like steel and glass fibres if…
resin or ceramics to strengthen the material. Carbon fibre is now overtaking traditional metals in where it is being used and the reasons why will be discussed further on in the report (Happian-Smith 2001: 1).
Carbon fibre composites have become the leading material in the automotive, aerospace and sporting equipment. This is due to its high strength, high young’s modulus and low density which makes it extremely lightweight for its properties. Carbon fibre composites with polymeric matrices have…
Low Carbon Steel
Low carbon steel is the most common form of steel with a low cost price while it provides material properties that are required for many applications. Low carbon steel contains a low carbon content and is therefore it is neither extremely brittle nor ductile. When heated, it becomes malleable and so can be forged. Low carbon steel is a very dense metal and has tensile strength has a max of 500 MPa.
Low carbon steel has 0.3% carbon which makes it one of the…
• Corrosion resistant
• Good tensile strength
• Good low and high temperature service
• Has a respectable friction coefficient
Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1, stainless steel rather than forming a rust layer like…
Discuss the effect of loading structural material
1) You need to discuss the effect of compressive force, tensile force, shear force, bending force on structural member
Compressive force on timber: - The effect of a compressive force on a timber is a change in structure of a material and to carry a load within its limits.
Tensile force on timber: - The tensile force is the pulling force exerted on both the ends of a timber. Both the ends of a timber will undergo…
obstacles such as rivers, valleys or lakes. Bridges are made of materials such as stone, wood, steel and concrete and the load acting on it can be mostly vehicles or pedestrians.
Bridges began to be used in ancient times by primitive people using natural resources such logs and slabs of rock. Then the Roman empires became the first great bridge builders and they used rocks and concrete to build Arch Bridges. Until the nineteenth century, Europeans built modern bridges using steel and…
second test is designed to compare the mechanical properties of native and autologous ACL ligaments from human cadavers and ligaments created from SRT protein. It is comprised of four subtests. First, we will test the tensile strength of all three ligament types at low, moderate, and maximal strain (relative to the strain experienced by native ligaments in the human body at resting, active, and extreme conditions) in an Instron 3360 Dual Column machine. Second, we will use one of each ligament…
