Stress is a measure of the load applied to a sample relative to a cross sectional area of the sample. Strength is a quantification of the samples ability to carry a load. The terms "yield strength" and "yield stress" of a material are usually used interchangeably (correct or not). It is the stress which will just cause the material to plastically deform. If a material yields at 30,000 psi, the yield stress is 30,000 psi. If the part in question has a cross sectional area of 2 square inches, the strength at yield would be 60,000 pounds, but usually we just say the yield strength is 30,000 psi.

Is yield strength and proof stress same?
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
What is the minimum yield strength of S235 steel?
It is its yield stress which is equal to 235 N/mm2
Is tensile strength of cold rolled steel is greater than yield stress?
For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.
Find the yield strength from a stress-strain graph?
Follow the graph's positive slope (across the first quadrant) until the graph is no longer linear. The yield strength is determined to be the last point (with concern given to the stress value) on the linear section. After this point the graph is irregular because the material has failed to a point of no return and can no longer handle the load (stress).
What is the yield strength of plywood?
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa
What is the difference between S275 and S355?
Difference in strength, 275 and 355 refer to minimum yield stress of the material (275 MPa and 355 MPa).
What is Characteristic yield strength of steel in terms of minimum yield stress and percent proof stress?
what is characteristic yield strength
Is yield strength and proof stress same?
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
What is the difference between yield strength and tensile strength?
Yield strength is a form of tensile strength, as yield strength is maximum strength upto which a material retains its original shape or it is in elastisity above which it will in plasticity.
What is the difference between Allowable Stress Design and Working Stress Design?
allowable stress design-2/3rd of yield working stress design is process yield
What is the difference between yield stress and proof stress?
yield stress is the maximum resistance to deformation per unit area and proof stress is the allowable resistance to deformation per unit area.
What is the difference between y42 and a 234 wpb pipe fittings?
yield strength
What is the minimum yield strength of S235 steel?
It is its yield stress which is equal to 235 N/mm2
What is the difference between low relaxation and stress relieved strands?
low relaxation strand differs from stress-relieved strand in 2 aspects: 1 - it meets more restrictive relaxation loss requirements 2 - the minimum yield strength at an extension of 1% is 90% of the specified minimum tensile strength, compared to 85% for stress-relieved strand.
What is the difference between proportional limit and yield strength?
Proportional limit is the maximum stress for which strain remains proportional to stress. As it is usually not obvious, industry accept to use offset method 0.0001 in/in. Yield stress is stress level which detrimental damage is assumed to occur (plasticity). This point is also not exhibited well in certain metal, so industry accept to use offset method 0.002 in/in.
What is the difference between BRC and BMC wire mesh?
Bmc with high yield strength 475 N/mm2
When use proof stress?
When the stress-strain curve of a material fails to produce a clear yield strength.
