I assume you mean the curve of length against applied force (or mass) for a wire. The beginning part of the curve should be a straight line, and this is where the deformation is elastic. When the substance passes its elastic limit, the line starts to curve up.

What part of the curve represents the elastic deformation of the material?

Stress strain curve for mild steel with detailed explanations?

the curve elastrate different, processes that are taking place with the deformation of the material,there is the elastic region the after plastic region which is followed by material being broken


What is the difference between deformation modulus and Young's modulus?

Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.


Why a stress-strain curve usually has two segments.?

Elastic - Plastic Deformation Ranges. Before and after yield point.


How does and engineer predict the performance and safety for a selected material?

There are a lot of test to be performed to get enough data for the research. Tensile test, hardness test, etc. Discovering the Yield Point, the Elastic and Plastic Deformation and the Fail Points on the Stress-Strain Curve. All the data is carefully collected and analyzed...


True or False the steeper the demand curve the less elastic the demand curve?

It is false that the steeper the demand curve the less elastic the demand curve. The steeper line is used in economics to indicate the inelastic demand curve.


Stress strain curve for brittle material?

Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.


What is Yield Strengths?

Yield strength is the stress at which a specified amount of permanent deformation of a material occurs. When we apply stress to a material, it deforms. Some of the deformation is plastic and the material can recover when the stress is relieved. But some deformation is permanent and the material cannot recover from it. As we apply more stress, there is more deformation. This plots on a curve in a somewhat linear, or proportional, way. But at some point, a bit more stress results in a lot more deformation, and this is the proportional limit of the material. Stress applied beyond this causes an increasing rate of deformation until the maximum or ultimate strength of the material is reached. (Beyond that it will fail completely.) Somewhere between the proportional limit and the ultimate strength of the material is the yield strength. The yield strength of a material cannot be calculated for any material. It must be arrived at through (repeated) experiment and statistical analysis. Use the link below to the related question, and the other links to related articles that explain more about yield strength.


Why is world supply curve horizontal?

The world supply curve is considered perfectly elastic.


An item's demand curve will be elastic when?

substitutes are unavailible


Under perfect competition is average revenue curve elastic or inelastic?

Under Perfect Competition the demand curve is perfectly elastic. I don't know if that helps but it might


When does supply curve look like a demand curve?

When supply and demand are perfectly elastic/inelastic
