UC001 – Compression testing:

Monotonic to max stress/strain


A uniaxial compression test is performed at a given crosshead speed. Strain is determined by measuring the local platen displacement using an extensometer (clip-on or non-contact, laser) or Digital Image Correlation (DIC). Testing can be done according to ASTM D575, ASTM D695, ISO 604 or other relevant compression testing standard. Veryst Engineering is ISO 17025:2005 accredited to perform this test according to ASTM D695.

Temperature Options

This test can generally be performed at any temperature between -80ºC and 280ºC.

  • CT: Cryogenic temperatures (-80ºC to 20ºC)

  • RT: Room temperature (~ 20ºC)

  • HT: High temperatures (20ºC to 280ºC)

Note: The use of the temperature chamber for high and low temperature tests limits the crosshead displacement for these tests.  Some combinations of material, temperature and specimen geometries may not be possible to complete to failure.

Strain Rates

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

Applicable Standards

ASTM D575, ASTM D695, ISO 604

Data Provided

Time, Engineering Strain, Engineering Stress, Load, Crosshead Displacement, Extensometer Measurement

Values Reported

Elastic Modulus, Yield Strength (0.2% offset), Ultimate Tensile Strength, Strength at Break, Extension at Break

Specimen Requirements

Cylinders, prisms or tubes with dimensions as specified in ASTM D575, D695 and ISO 604 are preferred. Comparable geometries are also possible.

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.
