11 Mechanical Properties of Material Every Mechanical Engineer should Know |
In Manufacturing to finalize or to handle engineering products fairly, it's become important to Understand all the basic Mechanical Properties of materials.
In this article we are going give brief discussion on the Mechanical Properties of materials, which every mechanical engineer should know to edge his/her skill.

Mechanical Properties
These are the properties which completely defines the behaviour of material under the action of external loads or forces.
In other words, The Mechanical properties are those properties which are associated with it's ability to resist failure as well as behaviour under the action of external forces.
Classification of Mechanical Properties:
Most of the mechanical properties are generally explained in terms of stress or strain.
Stress
It is defined as the internal resistance set up by the molecules of the material to resist deformation due to the application of action of external forces.

| Stress mathematical expression |
Strain
It is defined as the deformation or change in length per unit length under the action of external force.

3. Resilience
4. Stiffness
5. Ductility
6. Malleability
7. Brittleness
8. Plasticity
9. Toughness
10. Hardness
11. Creep
Let's discuss the mechanical properties of material in detail..
Strength
It is property of virtue of which it can be with stand or support an external force without rapture.
It is the resistance offered by a material when subjected to external load.
Elasticity
It is defined as the property of material by virtue of which it is able to retain its original shape and size after removal of load or external force.
Resilience
It is ability of material to a absorb energy when it is deform elastically.
Stiffness
It is also known as rigidity. It is defined as the property of Material by virtue of which it resist deformation and deflection under stress.
Ductility
Ductility is defined as the property of material by virtue of which it can be drawn into wires or elongated with the application of tensile forces, before after rupture take's place.
Malleability
The property of a material by virtue of which it can be rolled or hammered into thin sheet's without rupture by the application of compressive forces is called Malleability.
Brittleness
Lack of ductility can be termed as brittleness. It can be defined as the property of Material by virtue of which it will fracture or break without any deformation.
Plasticity
It is defined as the property of material by virtue of which are permanent deformation takes place, under the action of external force's.
Toughness
Toughness is the amount of energy a material can absorb before its fracture. This property is play as a vital role in the design of component which are directly subjected to impact loading.
Hardness
The property of material by virtue of which it's able to resist wear, stretching, penetration and surface deformation is called hardness. It is also means the ability of material to cut another material.
Creep
When a member is subjected to constant load over a long period of time. It undergoes slow permanent deformation and this is known as creep.
• Creep is dependent on temperature.
Homogeneous temperature is equal to the ratio of Testing temperature over melting melting temperature.
Conclusion:
By knowing all the basic mechanical properties of material one can easily work on them and edge their knowledge in Manufacturing.
