Tensile Stress-Strain, Strength, and Modulus
Test ID
M-204
Description
A universal testing machine (UTM) is used to determine modulus, tensile strength at yield or break, and stress-strain curves. The test specimen is loaded between the grips of the UTM. A mechanical (contact) or video (non-contact) extensometer is used to measure strain. The specimen is stretched at a constant speed while load and strain are recorded. The speed of testing is specified by the relevant standard.
NOTE: speeds below 1 mm/min are subject to a surcharge due to long test duration.
Options
Measurements at speeds slower than 1 mm/min are feasible. Additional charges may apply for long duration tests or if test temperatures exceed 200°C . In general, the minimum and maximum crosshead speeds are 0.3 mm/min and 500 mm/min (0.005 mm/sec and 8.3 mm/sec), respectively. Equivalent minimum and maximum strain rates may be determined, given the gauge length of the specimen type selected. For higher crosshead speeds, consult DatapointLabs tests M-232 or M-235.
