Planar tension testing: load/hold/unload

A planar tension test is performed at a specified strain rate.  The specimen is loaded to a specified strain or stress level, held at the specified strain or stress level for a desired amount of time (typically a few minutes) and unloaded to zero load.  This process is repeated for the desired number of load and unload cycles at the desired strain or stress levels.  Strain is measured using Digital Image Correlation (DIC).

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
Specimen 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.
