Description
A uniaxial compression 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 determined by measuring the local platen displacement using a clip-on extensometer or Digital Image Correlation (DIC).
Temperature Options
This test can generally be performed at any temperature between -80ºC and 280ºC.
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
Specimen Requirements
Cylinders, prisms, or tubes with dimensions as specified in ASTM D575, ASTM 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 usif you are interested in discussing this option.
Replicates Recommended
Two – five (2-5)
