High Speed Tensile Stress-Strain
A universal testing machine (UTM) is used. The test specimen is loaded between the grips of the UTM. A mechanical (contact) extensometer is used to measure strain up to a speed of 20000 mm/min. The specimen is stretched at a constant speed while load and strain are recorded. The speed of testing is specified by the relevant standard, or client request.

This test provides high strain rate stress-strain data for the simulation of impact situations. It is usually combined with stress-strain data spanning several decades of strain rates to create a rate dependant model of the material.
