What is 0.2 offset method?

For such materials, the yield strength σy can be defined by the offset method. The yield strength at 0.2% offset, for example, is obtained by drawing through the point of the horizontal axis of abscissa ε = 0.2% (or ε = 0.002), a line parallel to the initial straight-line portion of the stress-strain diagram.

Also asked, what is the minimum yield strength?

Specified Minimum Yield Strength (SMYS) means the specified minimum yield strength for steel pipe manufactured in accordance with a listed specification. It is an indication of the minimum stress a pipe may experience that will cause plastic (permanent) deformation.

What is yield strength of steel?

The yield strength (YS) is the stress at which a material begins to deform plastically and will not returns to its original shape when the applied stress is removed. The ultimate tensile strength (UTS) is the maximum stress that a material can withstand while being pulled before breaking.
