Planar Tension Testing
The planar tension test is designed to test the sample in a plane strain deformation state. The sample is a thin specimen with a width that is significantly larger than the height.
The graph below provides an example of the difference in response of a silicone rubber to planar tension versus uniaxial tension.
Veryst offers the following planar tension tests:
- PT001 - Planar tension testing: monotonic to max. stress/strain
Description
A planar tensile test is performed at a specified strain rate. Strain is measured using Digital Image Correlation (DIC)
- PT002 - Planar tension testing: load/unload (1 strain or stress level)
Description
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).
- PT003 - Planar tension testing, load/unload cycles
Description
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).
- PT004 - Planar tension testing, load/hold/unload cycles
Description
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).
- PT005 - Planar tension stress relaxation testing (up to 12 hrs.)
Description
A test specimen is loaded to a specified strain. The imposed strain is maintained for up to 12 hours and the stress/strain response of the material is measured. The specimen is unloaded to zero stress at the end of the specified time duration. Strain is measured using Digital Image Correlation (DIC).
- PT006 - Planar tension creep testing (up to 12 hrs.)
Description
A test specimen is loaded to a specified stress level. The imposed stress is maintained for up to 12 hours and the stress/strain response of the material is measured. The specimen is unloaded to zero stress at the end of the specified time duration. Strain is measured using Digital Image Correlation (DIC).
- PT007 - Custom load history
Combination of load/unload cycles and/or crosshead speeds
