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%).
