For Yield Point we have terms and definitions in 4 topics. The topics are Corrosion, Metal, Natural Gas and Steel.

Yield Point (Corrosion)

The first stress in a material, usually less than the maximum attainable stress, at which an increase in strain occurs without an increase in stress. Only certain metals - those that exhibit a localized, heterogeneous type of transition from elastic deformation to plastic deformation - produce a yield point. If there is a decrease in stress after yielding, a distinction may be made between upper and lower yield points. The load at which a sudden drop in the flow curve occurs is called the upper yield point. The constant load shown on the flow curve is the lower yield point

Yield Point (Metal)

The first stress in a material less than the maximum obtainable stess at which an increase in strain occurs without an increase in stress. Also known as upper yield stress.The first stress in a material, usually less than the maximum attainable stress, at which an increase in strain occurs without an increase in stress. Only certain metals exhibit a yield point. If there is a decrease in stress after yielding, a distinction may be made between upper and lower yield points.The load per unit of original cross section at which, in soft steel, a marked increase in deformation occurs without increase in load.

Yield Point (Natural Gas)

The stress at which a material exceeds its elastic limit. Below this stress, the material will recover its original size on removal of the stress. Above this stress, it will not.

Yield Point (Steel)

The load or stress at which a marked increase in the deformation of the sheet occurs without increasing the applied load. Yield point is one of the characteristics of low-carbon steels after they have been annealed. The yield point is usually calculated using a tensile-test specimen, and it is the load that is commensurate with the point beyond the elastic limit at which the specimen lengthens considerably without an additional increase in load.
