Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically. ... Stresses beyond the elastic limit cause a material to yield or flow.
What are some materials elastic?
Elastomers are elastic materials that regain their original shape if they are distorted. Some common elastomers are rubber , a naturally occurring polymer of isoprene, and neoprene, a synthetic polymer of 2-chloro-1,3-butadiene.
Why are some materials elastic?
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed . ... For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied.
Which material is more elastic and why?
The strain produced in rubber is much larger compared to that in steel. This means that steel has a larger value of Young’s modulus of elasticity and hence, steel has more elasticity than rubber. Note: Greater the resistance to change, greater is the elasticity of that material.
Why is material elasticity important?
This is useful for knowing how materials behave, material selection for device design, and calculating stress in a material since it is easier to measure deformation than it is to determine the exact force on a material. The modulus of elasticity is similar to the stiffness, k, of springs.
Which is the most elastic?
Elasticity is the ability of a material to regain its own original shape after being stretched according to which, rubber is the most elastic substance.
How do you know if material is elastic or plastic?
When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation. When the material goes back to its original form , that’s elastic deformation.
Is elastic a natural material?
Therefore, elasticity has to be artificially introduced into tissue-engineered scaffolds. The elasticity of scaffold materials can be attributed to either natural sources , when native elastin or recombinant techniques are used to provide natural polymers, or synthetic sources, when polymers are synthesized.
Is rubber elastic or inelastic?
It is this constant jostling that produces a resisting ( elastic ) force in the chains as they are forced to become straight. While stretching a rubber sample is the most common example of elasticity, it also occurs when rubber is compressed.
Is Cotton most elastic?
| Width | 1/4′′ | Color | Natural | Material | Cotton/Polyester | Stretch | 170% | Details |
|---|
Which is more elastic Mcq?
Air is more elastic than water.
Which metal is most elastic?
Steel is more elastic than rubber. The young’s modulus is the ratio of stress to strain.
Which is elastic material example?
The materials that can be stretched and when released attains their original shape and size are known as elastic materials. Rubber band is an example of elastic material.
What are the applications of elastic Behaviour of materials?
Application of Elastic Behavior of Materials
The theory of elasticity is used to design safe and stable man-made structures such as skyscrapers and overbridges to make life convenient . Cranes used to lift loads use ropes that are designed so that the stress due to the maximum load does not exceed the breaking stress.
What are the 3 modulus of elasticity?
Elastic Moduli can be of three types, Young’s modulus, Shear modulus, and Bulk modulus .
Which is least elastic material?
Rubber is the least elastic material.
