# Offset Yield Strength

Arbitrary approximation of elastic limit.

It is the stress that corresponds to the point of intersection of a stress-strain diagram and a line parallel to the straight line portion of the diagram.

Offset refers to the distance between the origin of the stress-strain diagram, and the point of intersection of the parallel line and the 0 stress axis.

Offset is expressed in terms of strain (often 0.2%).
