Tensile Stress-Strain, Strength, and Modulus

Test ID



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.


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 .
