Properties of Most Important Things of Our Daily Life:

Mechanical Properties of Materials

Introduction to Mechanical Properties of Materials:

 Materials that play an important role in everyday life. Imagine building without steel, cars without grey cast iron engines, and airplanes without titanium-aluminum alloys.

Well, Imagine this kind of thing is hard because without this there are no machines, no electrical appliances, and no computers.

Well, you know understand why materials are so important for us. Here in this article, we are talking about some mechanical properties of materials.

Mechanical properties of materials:

In this article, we discuss mechanical properties which are as follows:

1. Stiffness:

Stiffness is the ability of materials which cause resistance to elastic deformation. Well, after reading that you thought that it must break easily. But stiffness doesn't mean that it means it is hard to cause elastic deformation in that material.

For example, there is a rod of steel that can't bend easily but that does not mean it is not strong.

2. Malleability and ductility:

Malleability is the ability of materials by which is withstand compressive forces and turn that energy to change the shape of those materials. 

That ability makes that suitable to change shape under hammered and that why useful for converting materials into different shapes.

Ductility is the ability of materials by which is withstand tensile forces and convert energy to turn or change the shape of materials. 

That ability is suitable when we want to form long wires or when there is a condition when tension force acts on the workpiece.

Difference between malleability and ductility?

There is a difference between malleability and ductility is that in malleability forces act cause to push material inward. While forces in ductility cause a material to pull material outward.

3. Toughness:

Toughness is the ability of materials to absorb energy before being fractured. This is important property material. 

Let's suppose you want to build a rocket that lands on planets which has huge atmospheric temperatures and where you want materials that withstand large amounts of energy before fracturing.

4. Strength:

The strength is the maximum strength the materials withstanding before failure. 

But what is failure?

Before I researched this topic, I thought that failure is a fracture of materials. But cracking, wear and tear, and corroding all are the types of failure.

Let example, a titanium rod whose tensile strength is 240 MPa means stress higher than this level causes cracks, fractures, and so on. 

So, if you design spacecraft that land on a planet that applies force on spacecraft higher than 240MPa then do not use this material in that spacecraft.

5. Hardness:

Hardness is the ability of materials by which is cause resistance to plastic deformation.

6. Fatigue:

Fatigue is the weakening of material that occurs due to repeating cycles of stress. 

7. Brittleness:

Brittleness is the ability of materials which make them easy to break. Well, there are many brittle materials around us. Let's see glasses and so on.

Well, brittleness is the opposite of ductility. 

Conclusion:

Well, for this article we come to know that materials play an important role in our daily lives. And some of its mechanical properties. I hope you like this article. Thank you! For reading this article.
