Plus software to plot test results.
ASTM D638 (or ISO 527-1,-2) requires
tensile test machines for properties measurements of samples
as thick as 14 mm (0.55 inches). Each tester is configured with
special fixtures and software. Any TestResources tester is capable
of being equipped for a pull or tensile test using wedge action,
vise action, manual or pneumatic grips. Specimens are placed
in the grips of the tensile testing machine and pulled to elongation
at fracture, or failure. Test speed and grip separation are
defined in the test standard and depend on material properties.
The test requires measuring load and strain, or head travel
of the tensile tester machine head. In the case where the sample
elongates less than 20% and modulus is desired, a 50 mm gage
length extensometer is required. Load and deflection data can
be translated into a stress-strain curve, and tensile properties
extracted as shown:
- Tensile Elongation at Break or
Tensile Elongation at Rupture
- Tensile Elongation at Yield
- Tensile Strength at Break
- Ultimate Tensile Strength
- Tensile Modulus
- Secant modulus - materials that exhibit little or no linear
behavior. |

Modulus of elasticity calculations
can be made using grip separation values or with an extensometer
which produces more accurate data. ISO 527 allows for additional
specimen configurations, different test speeds, and requires
an extensometer. Users may employ a PC to setup and store test
parameters such as tensile rate or speed and monitor live test
results. Several choices of software are available including
those that generate test reports and exports data to Excel for
analysis.
