Yield stress is the point at which the material is no longer linear under load; the material starts to become plastic and when unloaded will not return to its original length. Typically the yield point is defined as 0.2% offset - the value of strain that remains in the part after unloaded
A yield stress is a value of sheer stress, below which a plastic acts like a solid, above which, a plastic deforms and a plastic material flows.
Elastic - Plastic Deformation Ranges. Before and after yield point.
in the haber process its yield is increased by increasing presure
Low Yield Low Yield
(13.6 g Actual yield/50.25 theoretical yield)*100=27% percent yield
A theoretical yield is equivalent to a percent yield of 100. In practice, it is very rare to achieve 100 yield from a reaction due to a wide range of outside factors 1.7mol
Yield stress is bigger than tensile stress.
what is characteristic yield strength
A factor of safety against yield is applied to design stress Yield Stress/ Design Stress = Factor of safety The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems
allowable stress design-2/3rd of yield working stress design is process yield
Yes it is the same. Offset Yield strength = 0.2% Proof Stress
Yield stress..
yield stress is the maximum resistance to deformation per unit area and proof stress is the allowable resistance to deformation per unit area.
flow stress is yield stress of material during plastic deformation

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.
It depends on the material. Most metals obey the maximum distortion energy law in which the shear yield is the tensile yield divided by square root of 3, or 0.577 x tensile yield.
It is its yield stress which is equal to 235 N/mm2
