Highest stress at which stress is directly proportional to strain. It is the highest stress at which the curve in a stress-strain diagram is a straight line. Proportional limit is equal to elastic limit for many metals.
The maximum stress at which strain remains directly proportional to stress; the upper end of the straight-line portion of the stress-strain or load-elongation curve.
Stress at which the deformation ceases to be proportional to the load as determined by straino-meter (also, by a extensometer for tension, compressometer for compression and deflectometer for transverse tests, value being read from plotted results). See "Elastic Limit."
is the greatest stress which a material is capable of sustaining without any deviation from the proportionality of stress to strain (Hooke's Law)
the point on a stress-strain curve at which the straight line proportionality between stress and strain ceases.-type Semiconductor a semiconductor for which the predominant charge carriers responsible for electrical conduction are holes. Normally, acceptor impurity atoms give rise to the excess holes.
As used in the rope industry, this term has virtually the same meaning as ELASTIC LIMIT. It is the end of the load versus elongation relationship at which an increase in load no longer produces a proportional increase in elongation and from which point recovery to the rope's original length is unlikely.
The stress above which stress is no longer proportional to strain, i.e., Hooke's Law ceases to apply (see Elastic Limit).
Maximum load at which strain or deformation is directly proportional to stress, at zero percent offset.
The greatest stress a material is capable of developing without a deviation from straight-line proportionality between stress and strain. See also elastic limit and Hooke's law.
The proportional limit is the maximum stress a material can undergo where the relationship between stress and strain are linearly proportional. This proportionality is known as Hooke's Law.
