What do you mean by elastic limit?
The elastic limit of a material is the maximum stress that can be developed within it without causing permanent deformation—or permanent stretch, in oil-field terms.
Real life Examples of Elastic Limit
Rubber is regarded as one of the most pliable materials. Glass is more elastic than steel and other materials. A nail bends permanently when subjected to the shear stress of a hammer strike, indicating that it has hit its elastic limit.
The elastic limit is a fundamental property of solid materials that determines the maximum amount of stress a material can handle before plastic deformation begins. It separates the recoverable (elastic) strain regime from the unrecoverable (plastic) strain region of the stress-strain curve.
Also called limit of proportionality, proportional limit.
Elasticity can be calculated by using Hooke's law: F = KΔL. Here, ΔL is the elongation, and a highly elastic material like rubber has a very small value of k because it can be stretched easily with a small force.
Explain what is meant by the elastic limit of the wire. -the maximum amount that a material can be. stretched (by a force) and still return to its original length when the force is removed. Define the Young modulus of a material and state the unit in which it is measured.
A high elastic modulus is typical for materials that are hard to deform; in other words, materials that require a high load to achieve a significant strain. An example is a steel band. A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band.
The elastic limit of a material wire depends on (i) the nature of material and (ii) the radius of the wire.
Thus, the steel possesses the highest elasticity among the given materials.
After reaching its elastic limit, a material or metal becomes deformed with the exertion of more force or stress. Elastic limit marks the end of elastic behavior and the beginning of a material's plastic behavior. Creating stresses beyond the elastic limit results in fracture for most brittle materials.
Does everything have an elastic limit?
An object designed to store elastic potential energy will typically have a high elastic limit, however all elastic objects have a limit to the load they can sustain. When deformed beyond the elastic limit, the object will no longer return to its original shape.
The opposite of elasticity is plasticity; when something is stretched, and it stays stretched, the material is said to be plastic. When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation.
An example is a steel band. A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band.
Stiffness: A stiff material has a high Young's Modulus. Deformation: Also known as plastic deformation, this is the warping that occurs under stress. Elastic limit: This is the limit beyond which the material is deformed. Yielding: Just beyond the elastic limit is permanent deformation known as yielding.
Osmium and iridium have the highest elastic moduli of any of the elements in the periodic table. They are less compressible and deform elastically less than other metals when subjected to shear and tension.
Hooke's law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.
Solids which break above the elastic limit are called brittle.
Non-linear extension and inelastic deformation can be seen above the limit of proportionality. The limit of proportionality is also described as the 'elastic limit'. The gradient of a force-extension graph before the limit of proportionality is equal to the spring constant.
The main difference between the elastic and the plastic material is the behavior of their structures. Elastic materials will break when they reach their elastic limit whereas the plastic material will not break.
Elastic Limit is defined as the point where a material can be stretched without causing permanent changes in the materials size or shape. If a material is stretched beyond the elastic limit, permanent deformation of the material will occur.
What if elastic is greater than 1?
If price elasticity is greater than 1, the good is elastic; if less than 1, it is inelastic. If a good's price elasticity is 0 (no amount of price change produces a change in demand), it is perfectly inelastic.
A product is considered to be elastic if the quantity demand of the product changes more than proportionally when its price increases or decreases. Conversely, a product is considered to be inelastic if the quantity demand of the product changes very little when its price fluctuates.
The elastic limit of steel is 8×108Nm−2 and its Young modulus 2×1011Nm−2.
Steel, because a body is said to be more elastic depending on how fast it gains its original shape after removal of external (deforming) force. When a force is applied to steel it is deformed but it immediately regains its original shape within a fraction of seconds which is not in the case of rubber.
A material's elastic limit is the greatest stress that can be applied to it without causing plastic (permanent) deformation. When a material is stressed to a point below its elastic limit, it will return to its original length once the stress is removed.
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. Hooke's law.

Elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed. Example: A rubber regains its shape after long stretch because of its elastic property.
The name yield strength seems to imply that it is the level of stress at which a material under load ceases to behave elastically and begins to yield. This is not the case. The point at which the material first begins to experience permanent set is known as the elastic limit (shown as the black line in Figure 1 below.)
The least elastic material among the given is rubber.
Why steel is more elastic than rubber?
The strain generated by rubber is substantially greater than that produced by steel. This indicates that steel has a higher Young's modulus of elasticity than rubber and hence has more elasticity. Hence, that is why steel is more elastic than rubber.
The most common goods with inelastic demand are utilities, prescription drugs, and tobacco products. In general, necessities and medical treatments tend to be inelastic, while luxury goods tend to be most elastic.
Greater the value of Young's modulus of a material, larger is its elasticity.
The higher the elastic modulus, the more resistant is the composite material to deformation within the elastic range. Flexural strength is more important in long-span restorations, as it refers to the strength of the composite when flexed between two points.
Rocks with low Young's modulus tend to be ductile and rocks with high Young's modulus tend to be brittle. Generally, brittle rocks have better completion quality and are better hydraulic fracturing targets. In practice, the estimated Young's modulus from sonic logs is termed dynamic Young's modulus.
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.
elastic material is those material which regains its shape and size after streaching. In language of physics the mercury is most elastic material.
- It has a Yield Strength of 260 Mega Pascals.
- Tensile Strength of 580 Moa.
- Around 6 on the Mohs scale.
- Is highly impact resistant.
The elastic limit is defined as the maximum stretch limit of the compression spring without taking a permanent set. It is a very common assumption that a compression spring would travel or can be compressed to its solid height. However, the compression spring has certain limit of flexibility considering its dimensions.
Examples of elastic goods include clothing or electronics, while inelastic goods are items like food and prescription drugs. Cross elasticity measures the change in demand for one good given price changes in a different, related good.
What objects have a low elastic limit?
A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band.
Rocks can bend and stretch up to a point. But once a rock's elastic limit is passed, the rock breaks. When rocks break in this way, they move along surfaces, or faults. A fault is the surface along which rocks move when they pass their elastic limit and break.
Elastic goods include luxury items and certain food and beverages as changes in their prices affect demand. Inelastic goods may include items such as tobacco and prescription drugs as demand often remains constant despite price changes.

elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
Rubber is the most elastic material, and glass would have the least elasticity. Elasticity is the capacity of a material to return to its former shape after being stretched.
Woven elastic—or “no roll”—is the strongest garment elastic. This elastic is easily identified by its horizontal and vertical ribs. This variety of elastic does not become more narrow as it stretches and does not lose resiliency when sewn.
Osmium and iridium have the highest elastic moduli of any of the elements in the periodic table. They are less compressible and deform elastically less than other metals when subjected to shear and tension.

What is the elastic limit of concrete?
The elastic modulus of the hardened paste may be in the order of 10-30 GPa and aggregates about 45 to 85 GPa. The concrete composite is then in the range of 30 to 50 GPa.
