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.
Similarly, 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.
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.
