Understanding The Different Mechanical Properties Of Engineering Materials.

Mechanical properties of materials are associated with the ability of the material to resist mechanical forces and load. These properties indicate how the material responds under specific stress, which helps to determine its suitability for different applications. The following are the common mechanical properties in engineering materials. 1. Strength. The strength of the material refers to the ability of the material to resist an externally applied force without breaking or yielding. That is the ability of a material to withstand an applied load without failure. Different types of material strength are compressive strength, tensile strength, shear strength, fatigue strength, torsional strength, bending or flexural strength, etc. For a more detailed explanation of material strength watch this video -    • Different Types Of Material Strength In En...   2. Elasticity. Elasticity is the ability of a deformed or stretched material body to return to its original shape and size after being stretched out or altered by a force. 3. Plasticity. Plasticity is the ability of a solid material to undergo permanent deformation, which is a non-reversible change in the shape of the object in response to an external force applied to it. 4. Ductility. Ductility is a mechanical property that describes the ability of a material to be stretched, pulled, or drawn into a thin wire and sustain plastic deformation without failure. It is the measure of how much a material can be deformed or elongated under stress before it fractures. 5. Brittleness. Brittleness refers to the property of a material that allows it to fracture or break abruptly under stress, without significant prior deformation. It is the breaking of a material with little permanent distortion. 6. Malleability. Malleability is the ability of a material to be rolled, flattened, or hammered into a thin sheet without cracking or breaking. It is the ability of a metal or metal alloy to be formed into a variety of shapes. 7. Toughness. Toughness is defined as the amount of energy that a unit volume of a material can absorb after being stressed up to failure. Toughness can also be understood as the measure of the resistance of a material to crack propagation and failure. Two major types of toughness include Fracture toughness and impact toughness. 8. Creep. When a part is subjected to constant stress at high temperature for a long period, it will undergo a slow and permanent deformation called creep. Creep occurs in three stages: primary creep, secondary creep, and tertiary creep. 9. Hardness. Hardness is the ability of a material to withstand localized plastic deformation such as indentation over an area, or a scratch induced mechanically either by pressing or abrasions. The three types of hardness are Scratch hardness, Indentation hardness, and rebound hardness. 10. Machinability. Machinability defines the ease at which a material (mainly metals) can be cut, shaped, or finished with any machining process. All these are discussed in this video.
