hooke's law
the largest stress for which Hooke’s Law applies or the highest point on the straight line potion of stress-strain diagram.
proportional limit
The largest stress to which a material can withstand without being permanently deformed. This term is synonymous with the proportional limit, that’s the reason that for structural steel it is also term as proportional elastic limit.
elastic limit
The stress at which there is a decided increase in the elongation or stain without a corresponding increase in stress.
yield point
The strain that occurs before yield point.
Elastic Strain
the strain that occurs after yield point.
Plastic Strain
a range following after the plastic stain where additional stress is necessary to produce additional strain.
Strain-Hardening
a sharp reduction in the cross section of a member taking place followed by failure.
Necking
the line portion in the stress-strain diagram of steel.
Elastic Range
