Many alloys do not show either a definite elastic limit or
yield point. Because of the importance of the yield point
to designers, calculations have been developed to produce
an artificial approximation. This approximation is known
as ‘proof stress’ and relates to a pre-determined amount of
permanent deformation measured against the strain axis.
A line parallel to the initial gradient of the stress strain
diagram is drawn. Where the drawn line and the curve
intersect is the proof stress . Proof stress is
most often calculated around the values of 0.1% and 0.2%
of the gauge length.
