Is the ratio of stress-strain in the region below the proportional limit on the stress-strain curve?
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
How many stress values can be found in stress strain curve?
An infinite amount... for any given Strain, there is a corresponding Stress value. To see what I mean, plot a Stress Strain graph in excel using 10 sets of values, then do another using 20... the one with 20 has a smoother curve, see where I'm coming from?
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.
Explain the significance of 0.2 percent offset in the stress strain diagram?
Theoretically, the yield strength of the material is the stress at which the stress-strain curve stops being linear. In actual testing of most materials, the transition to non-linear is not very clear in that area. The .2% offset line is used to intercept a yield stress for reporting a yield strength. Though arbitrary to a certain extent, it has become the traditional method.
How is a stress strain curve obtained?
From the origin O to the point called proportional limit, the stress-strain curve is a straight line. After reaching the proportional limit, the curve shows less stress until it gets to the ultimate strength, where the stress decreases.
Details about stress strain curve?

Where does the stress-strain curve end?
when the material fails
Is the ratio of stress-strain in the region below the proportional limit on the stress-strain curve?
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
How do you calculate the elastic limit?
By using stress-strain curve.
Why a stress-strain curve usually has two segments?
becuase its suppose to

What is strength coefficient?
Stress-strain power curve coefficient, K, numerically equal to the extrapolated value of true stress at a true strain of 1.00.
Explain why in tensile test the level of the true stress-strain curve is higher than that of engineering stress - stain curve?
see the following questionWhat_the_difference_between_true_strain_and_engineering_strain
What is 2 Secant Modulus?
This question probably is referring to a 2% secant modulus, which can be the tensile, flexural or compressive modulus (slope of a stress/strain curve) of a material that is determined from calculating the slope of a line drawn from the origin to 2% strain on a stress/Strain curve.
When use proof stress?
When the stress-strain curve of a material fails to produce a clear yield strength.
What is the difference between a stress strain curve and a load displacement curve?
a stress strain curve and a load displacement curve is pretty much the same thing, given the data is from the same specimen. its just the stress (force/area) is divided by a constant area and the strain (change in length/original length) is divided by a constant original length. therefore your curve would pretty much look the same as dividing by a constant will not change your graph. hope this explains your question
