The difference between the original cross-sectional area of the gauge length of a tensile specimen and the cross-sectional area at the point of fracture. This difference is usually then expressed as a percentage of the original cross-sectional area and the result used as a measure of the ductility of the metal being tested.
Measure of the ductility of metals obtained in a tension test. It is the difference between original cross sectional area of a specimen and the area of its smallest cross section after testing. It is usually ex-pressed as % decrease in original cross section. The smallest cross section can be measured at or after fracture. For metals, it usually is measured after fracture and for plastics and elastomers, it is measured at fracture.
The difference between the original cross-sectional area of a tensile specimen and that of the small-est area at the point of rupture. It is usually stated as a per-centage of the original area; also called "contraction of area."
(1) Commonly, the difference, expressed as a percentage of original area, between the original cross-sectional area of a tensile test specimen and the minimum cross-sectional area measured after complete separation. (2) The difference, expressed as a percentage of original area, between original cross-sectional area and that after straining of the specimen.
As determined in a tensile test this is the difference between the cross-sectional area of the test specimen and the smallest area at the point of rupture.
The percentage decrease in the cross- sectional area of a tensile test piece caused by wasting or necking of the specimen. It is expressed as a percentage of the original area of the test piece and is a measure of ductility.
The decrease in the area of the cross-section of a metal test specimen when fractured in tension testing. It is a criterion of ductility.
the diminution in section per unit of original area as applied to a bar that has been subjected to tensile forces and ruptured.
