Planar tension testing: load/unload (1 strain or stress level)

A planar tension test is performed at a specified strain rate.  The specimen is loaded to a specified strain or stress level and then unloaded at the same crosshead speed to zero load.  Strain is measured using Digital Image Correlation (DIC).

Example Data

PT002 Plot

Temperature Options
This test can generally be performed at any temperature between -80ºC and 250ºC.

  • CT: Cryogenic temperatures (-80ºC to 20ºC)
  • RT: Room temperature (~ 20ºC)
  • HT: High temperatures (20ºC to 250ºC)

Strain Rates
Strain rates up to ~ 1/s are possible, depending on specimen geometry.

Data Provided
Time, Engineering Strain, Engineering Stress

Specimen Requirements
Specimens must have a width-to-height ratio of 10:1.

Note that we request extra specimens to ensure a sufficient supply of specimens for valid testing.

Veryst can also assist in molding standard and non-standard test specimens.  Please contact us if you are interested in discussing this option.

Replicates Recommended
