Tensile test

Meaning in mechanical engineering, with examples

nounCommon term

In mechanical engineering, tensile test means: A test in which a standard sample is pulled until it breaks, to measure properties such as yield strength, tensile strength and elongation.

In Turkish: çekme deneyi, çekme testi

How it is used

Used in materials labs, quality control and material certificates. It is carried out on a universal testing machine according to standards such as ISO 6892-1 or ASTM E8. The result is a stress-strain curve and a test report.

Example sentences

  1. The tensile test results show a yield strength of 380 MPa and 24% elongation.

  2. We cut three samples from the plate for a tensile test.

Common collocations

  • tensile test specimen
  • tensile test results
  • carry out a tensile test
  • tensile strength
  • elongation at break
  • yield strengthThe stress at which a material stops behaving elastically and starts to deform permanently. Designers usually keep working stresses well below this value.
  • strainHow much a material stretches or shortens compared with its original length. It is a ratio with no unit and is often given in percent or in microstrain.
  • ductileAble to stretch and bend a lot before breaking. Most steels, copper and aluminum are ductile; glass and gray cast iron are not.
  • hardnessHow well a material resists being scratched, dented or worn at its surface. It is measured with tests such as Rockwell (HRC), Brinell (HB) or Vickers (HV).
  • inspectionChecking a part, product or machine against a drawing, specification or standard by looking at it, measuring it or testing it.
