Planar tension testing: load/unload cycles
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. 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).
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 up to ~ 1/s are possible, depending on specimen geometry.
Time, Engineering Strain, Engineering Stress
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.
