High Speed Tensile Stress-Strain


Test ID  
M-232

   
Description  
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.    
Standards  
ASTM D638

Application
 
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.
