Uniaxial Tension Testing

The uniaxial tension test is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (r-values).

Uniaxial tension tests are typically performed monotonically to failure at a single strain rate; however, Veryst commonly performs them at several strain rates, and includes multiple load cycles and/or stress relaxation periods to capture and characterize the complex behavior of polymers.

In addition to standard axial strain measurements using clip-on extensometers, Veryst also uses Digital Image Correlation (DIC) technology, which enables full-field strain measurements of the specimen as well as non-contact large strain (> 1000%) elongation measurements. 

 Veryst offers the following uniaxial tension tests:

Test ID Description
UT001 Tensile testing, monotonic to failure (i.e. ASTM D638, ISO 527 etc.)
UT002 Tensile testing, load/unload (1 strain or stress level)
UT003 Tensile testing, load/unload cycles
UT004 Tensile testing, load/hold/unload cycles
UT005 Tensile stress relaxation testing (up to 12 hrs.)
UT006 Tensile creep testing (up to 12 hrs.)
UT007 Custom load history - Combination of load/unload cycles and/or crosshead speeds
