Where does the stress-strain curve end?
when the material fails
Draw stress strain curve for mild steel?
Mild steel usually contains predominantly of Ferrite structure and it has got good ductility. The difference in stress-strain curve of Mild steel to other ductile materials is that it undergoes Multiple yielding. it occurs due to the fact that C and N segregate to dislocations.
How do you distinguish yield point and elastic limit?
On a stress strain curve the elastic limit is the point where the straight portion curve first starts to curve. When load is removed strain will return to zero. The yield point is a point on the curve just beyond the elastic limit. When load is removed strain will not return to zero. It will return approximately as a straight line parallel to the original, and have an offset strain value. The yield point offset is arbitrary but usually defined as 0.2% (.002 permanent strain) as most common strain devices can measure that amount.
How do impact energy from the charpy impact test correlates with stress-strain curve obtained from the tensile test?
jubo
What determines the slope of a material's stress verse strain curve?
The value of the Young's Modulus of Elasticity, which is an inherent property of the material
Why a stress-strain curve usually has two segments?

Why a stress-strain curve usually has two segments.?
Elastic - Plastic Deformation Ranges. Before and after yield point.
Details about stress strain curve?

Where does the stress-strain curve end?

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.
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?
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.
Draw stress strain curve for mild steel?
Mild steel usually contains predominantly of Ferrite structure and it has got good ductility. The difference in stress-strain curve of Mild steel to other ductile materials is that it undergoes Multiple yielding. it occurs due to the fact that C and N segregate to dislocations.
When use proof stress?
When the stress-strain curve of a material fails to produce a clear yield strength.
