उपज-बिंदु इसके अंग्रेजी अर्थ का उदाहरण

It is used to produce a smooth surface, a uniform thickness, and reduce the yield point phenomenon (by preventing Lüders bands from forming in later processing).

Lists of radio stations by frequency In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior.

Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed.

Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible and is known as plastic deformation.

The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically.

In some materials, such as aluminium, there is a gradual onset of non-linear behavior, making the precise yield point difficult to determine.

In such a case, the offset yield point (or proof stress) is taken as the stress at which 0.

In solid mechanics, the yield point can be specified in terms of the three-dimensional principal stresses (\sigma_1, \sigma_2 , \sigma_3) with a yield surface or a yield criterion.

Offset yield point (): When a yield point is not easily defined on the basis of the shape of the stress-strain curve an offset yield point is arbitrarily defined.

2} is multiplied by a factor of safety to obtain a lower value of the offset yield point.

High strength steel and aluminum alloys do not exhibit a yield point, so this offset yield point is used on these materials.

Upper and lower yield points: Some metals, such as mild steel, reach an upper yield point before dropping rapidly to a lower yield point.

The material response is linear up until the upper yield point, but the lower yield point is used in structural engineering as a conservative value.
